Emotional Expression01:26

Emotional Expression

Emotional expression encompasses how individuals convey their emotions through verbal communication and non-verbal cues. These non-verbal actions include facial expressions, body language, and physical gestures, such as frowning or smiling. Among these, facial expressions play a crucial role in emotional expression and are understood universally, indicating a biological basis for how humans communicate emotions.

Non-Verbal Cues01:29

Non-Verbal Cues

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...
Labeling Emotion01:20

Labeling Emotion

Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...
Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
Physiology of Emotion01:20

Physiology of Emotion

The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...
Therapeutic Communication01:30

Therapeutic Communication

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Area of Science:

  • Human-Computer Interaction (HCI)
  • Artificial Intelligence (AI)
  • Speech Synthesis and Recognition

Background:

  • Investigating emotion in synthesized audio-voice signals is crucial for advanced user interface design.
  • Current text-to-speech (TTS) technologies offer opportunities to imbue artificial voices with emotional expression.

Purpose of the Study:

  • To formulate a theory of expression for user interface design based on synthesized emotional audio.
  • To explore the artistic and psychological implications of artificial speech emotion.
  • To develop interdisciplinary tools for artificial voice research.

Main Methods:

  • Emotional parameters were defined using markup tags and refined with post-processing techniques.
  • Software was created to integrate a TTS synthesizer with an automatic speech recognition (ASR) engine, forming a conversational agent.
  • The capabilities of this artificial voice system were explored for various applications.

Main Results:

  • A chatbot capable of synthesized speech and auditory recognition was successfully developed.
  • The study explored both artistic and psychological dimensions of artificial voice emotion.
  • Initial findings suggest an emerging interdisciplinary ontology for artificial voices.

Conclusions:

  • The research provides a foundation for understanding and implementing emotional expression in synthesized speech.
  • Proposed HCI tools aim to facilitate future collaborative efforts in artificial voice development.
  • This work bridges disciplines including AI, HCI, and communication technologies.
