Features
What is text to speech?
Text to speech (TTS) is technology that turns written text into natural, spoken audio. Modern AI voices sound close to a real human, so you can listen to articles, documents and scripts instead of reading them. SaydiVoice runs in your browser, supports many languages, and lets you download the result as MP3 or WAV.
Text to speech online, with nothing to install
SaydiVoice runs entirely in your browser. There is no software to download, no extension to add and no microphone needed — open this page on a computer or a phone and it works. The text you paste is turned into an audio file in seconds.
If you are looking for a text to speech app, the browser on your phone is enough: open this page in Chrome or Safari, paste your text, pick a voice and download MP3 or WAV. The first few runs need no account.
How to make a text to speech voice sound natural
How natural the result sounds depends a lot on how the text is written. A few small edits usually make a bigger difference than switching voices.
Punctuation is the cheapest way to control pacing: a comma gives a short pause, a full stop a longer one, an ellipsis a trailing one. Short sentences and a line break between ideas also stop the delivery from flattening out.
AI text to speech compared with recording a real voice
Both work. The practical question is what your content needs: a real voice for a personal touch, or speed and low cost at volume.
| AI voice (SaydiVoice) | Recording a real voice | |
|---|---|---|
| 10 minutes of audio | A few minutes | 1-2 hours including editing |
| Cost | Free 50,000 characters a month | Studio time and a voice actor |
| Fixing one wrong line | Edit the text and regenerate | Re-record the whole take |
| Switching language | Pick another voice and language | Needs a native speaker |
| Voice library | 1,000+ voices, 30+ languages | Whoever you can book |
| Emotion | Emotion tags: sad, happy, urgent | The most natural |

Free text to speech — where the limits actually are
SaydiVoice really is free to use, with limits you can plan around: the free plan includes 50,000 characters a month and up to 3,000 characters per run. That is enough for roughly 30-50 short videos a month.
Anything longer than 3,000 characters belongs in the studio — it takes long scripts, several voices in one piece and exports MP3 or WAV. The first few runs need no account; to keep going you sign in free with Google, Facebook or email.
