        Emotion recognition and digital empathy are visionary goals of research conducted
within the areas of Human Computer Interaction (HCI) and Affective Computing [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
Despite a myriad of data produced by sensors, detectors and Internet of Things (IoT)
devices, and also the analysis conducted thereon, effective emulation of human emotion
recognition remains a challenge for interactive artificially intelligent agents [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ].
Typically, humans are emotive beings. Mood, feelings and emotions are woven into our
interactions. They are conveyed by voice tone and intonation, facial expression, bod y
language and a plethora of other social behaviours. Despite all these cues, some
individuals still struggle with understanding the emotion of others. Alexithymia is defined
as “a personality construct characterized by the sub-clinical inability to identify and
describe emotions in the self and others” [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. Sufferers of Alexithymia display marked
dysfunction in interpersonal relating, social attachment and emotional awareness [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
Due to challenges in distinguishing and understanding emotions of others, the
behaviours of alexithymics can appear un-empathic. The latest generation of intelligent
agents housed by voice command devices (VCDs) may be able to support daily
routines, but lack key indicators of emotional understanding and empathy [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ].
      </p>
      <p>
        VCDs offer a new paradigm for mainstream human interaction with artificial
intelligence. These devices are becoming increasingly commonplace in domestic
environments [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. They provide access to intelligent personal assistant services that are
designed to synthesize and streamline various aspects of daily life [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ]. These devices are
changing the way that people think about and interact with their environments. The
influx of VCDs has the capacity to contribute a multitude of worthwhile and novel
features that aid and improve the user experience when executing conventional tasks .
The Amazon Echo [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] is currently one of the most popular and pervasive of these
devices. The associated intelligent agent, ‘Alexa’ is capable of demonstrating human-like
conversational ability, however her unemotive responses would allow all but the most
primitive human minds to quickly establish that she is not human [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. Alexa clearly
neither recognises nor truly displays any emotion, therefore it could be posited that
Alexa may suffer from Alexithymia! Whether the similarity in name is by design or
coincidence, it is evident that a cure for this condition is a goal belonging to Amazon’s
developers. This research explores the means by which VCDs may infer an individual’s
emotional state, thereby reducing prevalence of Alexithymia in AI.

      <title>Background</title>
      <p>This section provides background for the research, offering information that relates
to the disciplines, technologies, models, associations and considerations concerned.

      <sec id="sec-2-1">
        <title>Affective Computing</title>
        <p>
          Affective computing is an emerging interdisciplinary research area that combines
various fields, ranging from artificial intelligence and natural language processing, to
cognitive and social sciences [
          <xref ref-type="bibr" rid="ref9">9</xref>
          ]. A main goal of affective computing is to develop systems
capable of adapting to users’ emotions in order to produce more natural and efficient
interaction. Thus, a central component of the field is emotion recognition based on a
variety of measurements including facial expressions, speech, gait patterns and other
metrics that are analysed using advanced pattern recognition techniques [
          <xref ref-type="bibr" rid="ref10">10</xref>
          ]. Although
there have been great advancements in the field, only a few robust implementations
have been presented or validated, thus adoption of affect-aware technology has been
marginal [
          <xref ref-type="bibr" rid="ref1">1</xref>
          ].

        <title>Voice Command Devices</title>
        <p>
          Becoming increasingly popular, these devices are typically interactive and function
to gather metrics and support many aspects our lives [
          <xref ref-type="bibr" rid="ref7">7</xref>
          ]. While keyboard and pointer
input have traditionally been the means of human-computer interaction, since 2012
there has been a significant drive [
          <xref ref-type="bibr" rid="ref11">11</xref>
          ] to enable hands free control, primarily by voice.
Figure 1 depicts the operation of Voice Command Devices.
        </p>
        <p>
          The Amazon Echo provides an artificially intelligent personal assistant referred to
as ‘Alexa’, who possesses a range of functionality and ‘skills’ which enable voice
activation and communication with numerous IoT devices. These include wearable health
devices, shopping lists, streamed music services and calendars, amongst others [
          <xref ref-type="bibr" rid="ref6">6</xref>
          ].
Following use of the ‘wake word’ that activates the VCD, interactions and data harvested
is subsequently stored in the parent company’s cloud.

      <sec id="sec-2-3">
        <title>Emotion Recognition</title>
        <p>
          Emotions are physiological, behavioural, and/or communicative reactions to stimuli
that are cognitively processed and experienced [
          <xref ref-type="bibr" rid="ref12">12</xref>
          ]. They are often internally
experienced through physiological changes such as increased heart rate or a tense stomach
[
          <xref ref-type="bibr" rid="ref13">13</xref>
          ]. These physiological reactions may not be detected by others and are considered
intrapersonal unless there is a verbal or non-verbal cue that indicates the internal state
and these cues may be voluntary or involuntary [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ]. When communicating, cues in
verbal intonation and body language provide information to others relating to how they
should react. For example, when someone exhibits behaviours associated with sadness,
it is an indication that support is needed [
          <xref ref-type="bibr" rid="ref12">12</xref>
          ]. Humans typically learn through
socialisation how to read and display emotions.
        </p>
        <p>
          Emotion recognition describes the process of identifying emotion in humans. The
cognitive mechanisms invoked in recognizing human emotion have been studied for
hundreds of years. The fields of psychology and more recently those such as cognitive
science, have developed a range of models in this area. The most recent models rely
on AI through use of signal processing, machine learning, natural language processing
(NLP) and other modern implementations [
          <xref ref-type="bibr" rid="ref15">15</xref>
          ].
        </p>
        <p>
          Within emotional recognition, signals detected by all five senses (sight, sound,
touch, scent and taste) may be recruited to enable one human to recognize, process and
understand the emotions of another human. However, typically the signals that are
relied upon most heavily are those that are visual and produce sound [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ]. Sight allows
a human to process and understand facial expressions and body language relating to
particular emotions. Hearing enables the emotion to be revealed through analysis of the
language, pitch, tone and volume of a human voice [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ]. These signals are transmitted
to the brain, combined and analysed so that the emotion may be deduced. Humans have
come to rely heavily on use of language to recognize the emotion of another since the
advent of voice telecommunications and written correspondence [
          <xref ref-type="bibr" rid="ref16">16</xref>
          ]. Figure 1
displays a subset of the means by which a person may sense the emotion of another person.

        <p>
          Currently, there is significant research in progress that focuses primarily on facial
expressions, NLP and voice characteristics in a bid to help machines to learn to achieve
emotion detection and recognition in a way that emulates human ability [
          <xref ref-type="bibr" rid="ref17">17</xref>
          ]. Research
has also indicated that analysis of gait and posture may also reveal indicators of emotion
[
          <xref ref-type="bibr" rid="ref18">18</xref>
          ]. Additionally, studies of human behaviour and social interactions may also contain
clues relating to the emotional state of a person. EEG, ECG and MRI medical
technologies facilitate the scanning of brains and bodies, these enable researchers and medical
professionals to detect emotion associated neural signals that allow emotion detection
and classification beyond the instinctive and learned mechanisms invoked by humans
[
          <xref ref-type="bibr" rid="ref18">18</xref>
          ]. Although there are many indicators that may be examined when using modern
technology to detect and classify emotion, current successful models rely heavily on
facial expression and textual analysis. The Amazon Echo device currently lacks the
capacity to analyse facial expression and body language. Its resident intelligent agent,
Alexa, must rely primarily on sound and interactive behavior [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ].
2.3 Emotion &amp; Voice Command Devices
        </p>
        <p>
          Replicating the emotion detection capability of people within intelligent agents such
as Alexa is an increasingly popular and innovative field of research [
          <xref ref-type="bibr" rid="ref20">20</xref>
          ]. Work in this
area spans multiple related disciplines including AI, ML, NLP, Human Computer
Interaction (HCI), Robotics and Affective Computing. Artificial sensors such as vision
systems, microphones, thermo-detection devices, body electro sensors, magnetic
resonance detectors, heart-rate monitors and sweat detection devices all produce data that
may be analysed to elicit patterns that correspond to emotions [
          <xref ref-type="bibr" rid="ref20">20</xref>
          ]. Challenges arise
when the number and variance of sensors or modalities is limited. However, inference
may be used to ‘fill in the gaps’ and deduce emotions based on the data that is available.
Popular systems that are invoking inferential data to overcome these challenges are
embodied in Voice Command Devices such as the Amazon Echo [
          <xref ref-type="bibr" rid="ref21">21</xref>
          ]. The range of
sources that contain data with which emotion may be detected by the Echo are displayed
in Figure 3.
        </p>
        <p>The majority of VCD devices are limited to speech which allows for NLP of the
words spoken and analysis of the voice characteristics. This may be achieved by
processing the harvested data in the Cloud via a combination of “Big Data” sets, ML
algorithms and the vast Compute Power resources available as depicted in Figure 4.</p>
        <p>By enabling VCDs to act as hub for IoT devices and a myriad of applications, the
manufacturers have gained access to a rich tapestr y of data that relates to an individual’s
emotional state. Once collated and analysed, this data enables emotional state inference
on a scale heretofore unknown. Furthermore, the data available to these data hungry
organisations is increasing exponentially with the increased popularity of these voice
command and IoT devices.</p>
        <p>
          The parent companies such as Amazon who manufacture these devices are primarily
‘sales organisations’ and it is in their interests to market effectively. A good sales
person knows their customer and the more they know, the higher the probability of making
a sale [
          <xref ref-type="bibr" rid="ref22">22</xref>
          ]. Awareness of a potential customer’s emotional state is extremely useful to
many different types of organisations. Targeted advertising and the associated
psychographic models are yielding significant returns on investment. The addition of
“EMOTOGRAPHIC” models could further increase the selling power of these
companies as shown in Figure 5.
        </p>
      </sec>
      <sec id="sec-2-4">
        <title>Detecting the Emotion of Sadness</title>
        <p>
          Emotional state and mental health have become a key focus for health organisations,
governments and various other organisations in the last decade [
          <xref ref-type="bibr" rid="ref23">23</xref>
          ]. Traditionally
individuals suffering from afflictions such as depression will consult a health practitioner
to have their mental health assessed to detect their emotional state. Mojtabai [
          <xref ref-type="bibr" rid="ref24">24</xref>
          ]
describes that this is typically achieved by way of standard questions such as ‘How well
are you sleeping?’ (MADRS), ‘How are your energy levels?’ (Beck Depression
Inventory) or ‘Have you had any thoughts of suicide?’ (HAMD). Figure 6 depicts some of
the inferential indictors of the emotion of sadness which also tend to be associated with
the condition of depression [
          <xref ref-type="bibr" rid="ref24">24</xref>
          ]. This type of data is both interesting and valuable to
organisations such as governments, pharmaceutical companies and marketing groups.
        </p>
        <p>Currently verbal responses from VCDs like Amazon’s Echo do not give an
indication that the devices understand emotion in humans. However, when analysis is
performed on the intonation of verbal communication and data gathered from searches and
linked devices such as Fitbit or music selected through streaming services, patterns may
be detected that give insight to the emotional state of the user. Despite the unemotional
nature of the device itself, this type of inferential data may still be collected by parent
companies for use in the development of ‘Affective’ devices. Additionally.
‘state-ofmind’ has the capacity to greatly impact the needs, behaviour and habits of individuals.
No matter how arbitrary, this type of data is valuable and sold to other various entities
for purposes such as targeted marketing.</p>
      </sec>
    </sec>
    <sec id="sec-3">
      <title>Methodology</title>
      <p>
        The target VCD was an Amazon Echo that had been configured for a domestic
environment and was interacted with by a single primary user over a period of five
months. This device has also been configured to link to a range of external applications,
as reported in [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. Data gathered by the external applications has the potential to be
utilised as a form of non-verbal information which may enable Alexa or the parent
company Amazon to infer the emotional state of the user.
      </p>
      <p>For the purposes of this paper it was decided to focus on sadness, one of the most
common emotions that potentially may lead to an active condition of depression. To
elicit information which would indicate potential levels of depression, a short
experiment was conducted. A script was developed which outlined queries to be posed to the
Amazon Echo VCD. These questions were designed to:</p>
      <p>a) Establish Alexa’s current ‘knowledge’ relating to the primary users’ levels of
sadness and depression. This was done in order to document verbal responses that would
be offered to the same type of direct questions that would be posed by a health
practitioner.</p>
      <p>b) Establish if inferential data collected from connected devices could potentially
give an indication of the primary user’s emotional state.</p>
      <p>A test environment was constructed where an Amazon Echo VCD with default
configuration was linked to several accounts, applications and IoT devices through the
standard settings. It should be noted that an Amazon account is a mandatory
requirement for configuring the Amazon Echo. Table 1 lists the devices, accounts and
applications that were linked to the VCD for testing purposes.</p>
    </sec>
    <sec id="sec-4">
      <title>Results &amp; Discussion</title>
      <p>This section offers an excerpt from the query script and responses in Table 2. In
addition, a summary of the information gained is included. Each example lists the
question that would be posed by a healthcare professional, the equivalent question posed to
Alexa to return the desired information and also the VCD’s response. Informati on
gained directly from the Alexa application is also shown in Table 2.</p>
      <p>The Alexa application documents a history of all interactions with the Echo device.
The application also documents a list of all the music selections played via Amazon
music. When linked with a wearable fitness tracker such as Fitbit, the device al so relays
information relating to the sleep patterns and activity/energy levels of the primary user.
Although subtle, the combined inferential information gathered from these devices has
the potential to indicate the emotional state of the user. This may be achieved though
application of natural language processing algorithms to extract the key words that
relate to emotion. Through these mechanisms there is the facility for the parent company,
in this case Amazon, to harvest, analyses and potentially profit from the data collected.</p>
      <p>This paper illustrates the ease by which indicators of emotions such as sadness, and
indeed the associated condition of depression, may be elicited from an individual
Amazon Echo device. While the probable value of this observation in terms of improving
health and providing emotional support are clear, for parent companies such as
Amazon, more lucrative applications of the data exist. This is inclusive of more effective
and accurately targeted advertisements and recommendations. Ethically this is
questionable, as the implications of this are significant when based on patterns detected
relating to user emotion and potential mental health.</p>
      <p>Amazon is primarily a retailer and the more effective the company is at marketing
through target advertising, the more profitable they will become. Algorithms that
indicate whether an individual may be suffering from depression could potentially lead to
an unethical advertisement for medication, exercise programmes, dietary advice and
counselling services. While these targeted advertisements may be helpful to the
individual, companies like Amazon will increase revenue based on the unethically gathered
inferential data relating to consumers.

      <title>Conclusion</title>
      <p>Although emotional recognition and digital empathy are idealistic goals wi thin the
development of AI and intelligent agents, the current technology available lacks
outward emotional understanding and the personas contribute only alexithymic responses.
Despite extensive research by large multinational technological organizations,
authentic human-like empathic interactions with intelligent agents have not yet been achieved.

      <p>This paper has demonstrated that despite Alexa’s demonstrated lack of emotion and

      <p>As VCDs incorporate improved implementations of affective computing, the ability
to build user trust as well as communicate an understanding of emotions will only
increase. This potentially leads to great ethical and privacy concerns as intelligent agents
such as Alexa are gradually and incrementally cured of Alexithymia indicators.</p>
