A Survey on Human-Centric Voice-Face Multimodal Learning
Summary
This survey systematically reviews voice-face multimodal learning, integrating speech and facial data for human behavior analysis. It categorizes research into five key areas, highlighting challenges and future directions for this interdisciplinary field.
Area of Science:
- Multimodal Learning
- Human-Computer Interaction
- Cognitive Science
Background:
- Voice-face multimodal learning integrates speech, nonverbal acoustics, and facial data for understanding human behavior.
- Existing research often lacks a holistic view, remaining task-specific and overlooking unique human-centric learning properties.
- This field draws upon biometric and neurocognitive principles for analyzing human-centered patterns.
Purpose of the Study:
- To provide a systematic overview of voice-face multimodal learning.
- To categorize existing research into five key areas: foundations, task evolution, representation learning, datasets, and bias.
- To unify fragmented research and identify future directions.
Main Methods:
- Systematic literature review and categorization of research.
- Analysis of biometric and neurocognitive foundations.
- Examination of task evolution, representation learning, dataset taxonomy, and demographic bias.
- Review of past approaches and recent advancements in downstream tasks.
Main Results:
- Research is categorized into five core areas, providing a structured understanding of the field.
- Identified hidden dependencies between tasks through evolutionary trajectory analysis.
- Highlighted the importance of human-centric representation learning and dataset properties.
- Analyzed demographic bias and task-specific edge cases for fairness and robustness.
Conclusions:
- A holistic perspective is needed to address the interdependencies in voice-face multimodal learning.
- Further research is required in human-centric representation learning and dataset design.
- Addressing bias and edge cases is crucial for robust and fair human-centric AI systems.

01:24Facial 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...
01:15Sensory Modalities
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:22Purposive Learning
E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a bonus...
01:21Cognitive Learning
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:12Observational Learning
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning because...
