Open-source text-to-speech tuned for natural conversation
Tuned for dialogue rather than narration, so output carries natural rhythm, pauses and intonation that suits assistant-style speech.
Handles both languages, making it practical for multilingual assistant experiences and content that switches between them.
Code and pretrained weights are publicly available, so you can run it locally, inspect it and fine-tune it on your own audio.
Install with pip, load the model, pass a list of text strings and receive waveform arrays ready to play or save.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
SpecialistDelivers significantly superior voice realism and cloning quality, but lacks Speechify's dedicated document library reader interface.
Free / Open-sourceProvides powerful open-source speech synthesis and voice cloning, but requires technical setup compared to turnkey apps.
Offers a very similar document-reading experience and browser extension for listening to PDFs, but with fewer advanced voice cloning suites.
