What This Research Area Covers
Speech AI research covers converting spoken language into text (speech recognition), converting text into natural-sounding speech (synthesis), and understanding speaker characteristics like emotion and identity.
Why It Matters
Voice remains one of the most natural ways humans communicate, and reliable speech AI underpins voice assistants, transcription tools, and accessibility technology used at massive scale.
Current Research Directions
Improving accuracy across accents and noisy environments, more natural and expressive speech synthesis, and reducing the data and compute needed for high-quality speech models are all active areas.

Frequently Asked
What's the difference between speech AI and audio models generally?
Speech AI specifically focuses on spoken language; audio models research covers a broader range including music and general sound — see our Audio Models page.
What is Whisper?
An influential open speech recognition model from OpenAI, widely adopted for transcription tasks.
Why is accent and noise robustness still a challenge?
Real-world audio conditions vary enormously, and models trained predominantly on clean, standard-accent data can perform less reliably outside those conditions.
Where can I find speech-related tools?
See our Tools directory for transcription and speech-related platforms.
