Text-to-Speech and Speech-to-Text
Last updated 8 Nov 2026
Text to speech
Voices from ElevenLabs, OpenAI and Google. Pick a voice and get spoken audio for your text; the price depends on the model and the length of the text.
Speech to text
Transcription runs on OpenAI and Groq (Whisper) models. Attach a recording in chat, or use live transcription — see /docs/doc-live-transcription.
Realtime voice
Talk with the assistant in real time and hear it answer — see /docs/doc-realtime-voice-and-live-translation. Realtime sessions are billed by the minute.
Languages supported
TTS and STT cover the major world languages and many more. Quality varies by language and provider: the most widely spoken languages get the most natural voices, and transcription accuracy follows the training data available for each language.
Watch how it works
Live translation, live transcription and translated video subtitles with AI
Choose the language you speak and the one to translate into, and start talking: your voice is translated as you go. It works one direction at a time; tap swap and the other person answers in their own language, and the whole conversation can be saved as a note. Live Transcription writes down what you say in real time, Speech-to-Text turns a recording into text, and a video comes back with its transcript, its translation and subtitle files in both languages.
