Text to Speech Online — Free Neural Voices

The tool offers 88 Microsoft Neural voices covering 30 languages and regional variants. This includes English (US, UK, AU), Russian, Korean, Arabic (SA, EG), Indonesian, Spanish, French, German, Portuguese, Italian, Japanese, Chinese (Mandarin, Cantonese), Hindi, Turkish, and more.

Your text is sent to our server, which connects to Microsoft's neural speech service via a secure WebSocket to generate audio. The text is used only for the duration of the synthesis request.

The limit is 5,000 characters per generation (text longer than this is truncated by the input field). For longer texts, split them into parts of up to 5,000 characters, generate each separately, then join the resulting MP3s with our /audio-join tool.

Yes! Wrap a word in asterisks like *this* to add emphasis (the voice will stress that word). Type /pause/ for a short 500ms silence, or [pause 5s] for a longer pause (any value from 100ms to 30s — useful for guided exercises and meditations). These markup options give you fine control over the speech output.

The speech is generated natively in MP3 format (24kHz, 48kbps). You can also download as WAV — the tool converts MP3 to WAV directly in your browser using the Web Audio API.

Auto-detection works best with sentences (3+ words). For very short text or mixed-language content, select the language manually from the dropdown. The tool detects language by analyzing Unicode script ranges and common word patterns.
