AI Glossary

Speech AI

Speech AI covers recognition, synthesis, and understanding of spoken language in products and research systems.

Definition

Speech AI covers recognition, synthesis, and understanding of spoken language in products and research systems.

Plain English explanation

AI that listens to and/or speaks human speech.

Technical explanation

Speech AI systems perform recognition (ASR), synthesis (TTS), speaker tasks, and spoken-language understanding, often combining acoustic models with language models.

Why it matters

Voice interfaces and transcription are core enterprise and accessibility workflows. Separating speech from generic NLP clarifies vendor comparisons.

Real-world applications

  • Meeting and call transcription
  • Voice assistants and IVR modernization
  • Accessibility captioning

Benefits

  • Converts speech to searchable text
  • Enables hands-free interfaces

Limitations

  • Noise and accent robustness vary
  • Privacy risks for always-on audio

Common misconceptions

  • Speech AI is not only consumer gadgets—enterprise transcription is a major category
