Complete Guide: How to Convert Text to Speech with Neural AI Voices
Our text-to-speech tool gives you two ways to convert text to audio — instant browser playback and downloadable neural voices in 25+ languages — all running privately in your browser without uploading any data.
Enter Your Text
Type or paste the text you want to convert. Use [pause] or [pause=800] markers to insert natural-sounding pauses between sentences.
Choose Your Engine
Select Browser voices for instant playback with pitch, speed, and volume controls. Or stay on Browser voices and use the Generate & Download section to produce a downloadable neural audio file.
Pick a Language for Neural Voice
In the Generate & Download section, select from 25+ languages including Arabic, Hindi, French, Japanese, and more. The model (~10 MB) downloads once and is cached in your browser.
Click Generate
The neural voice model runs entirely in your browser and synthesizes the audio. No data leaves your device.
Download WAV or MP3
Once generation is complete, choose WAV for maximum quality or MP3 for a smaller file size — then use it in any video, podcast, or presentation.
Pro Tips
- Use punctuation to control pauses and natural intonation in the generated speech.
- For non-English languages, make sure your text is written in the correct script — Latin text will not work with a Hindi or Arabic model.
- Click 'Use example text' to try a pre-written sample in the selected language.
- The neural voice model is cached after the first download — switching back to the same language is instant.
Common Issues
Audio sounds like noise or static?
You are using Latin text with a non-Latin language model (e.g., English text with the Hindi model). Make sure the text matches the selected language's script. Use the 'Use example text' button to try a correct sample.
No browser voices available?
Some browsers or OS configurations have no built-in voices. Use the Generate & Download section instead — it works independently of browser voices.
