Definition
In artificial intelligence, voice encompasses the acoustic signals generated by human vocal cords that carry linguistic information. It is distinct from general audio as it specifically relates to spoken language. AI models process voice through Automatic Speech Recognition (ASR) to convert audio to text, or through Text-to-Speech (TTS) to synthesize natural-sounding speech. Key characteristics include pitch, tone, and timbre, which can also convey emotional context and speaker identity, enabling more nuanced human-computer interactions.
Summary
Voice refers to the human sound produced by speech, which serves as the primary input modality for speech recognition and synthesis systems.
