Text to Speech
Configure Edge TTS voices by language and tune speaking rate, pitch, and volume for Read Frog tools.
Open Options → Text to Speech to configure the voice used by Read Frog's Speak actions. TTS is currently labeled Public Beta, but it does not require enabling Beta Experience.
Where speech is available
The selection toolbar can show a Speak action for selected text. Other Read Frog surfaces may also expose speech when TTS is enabled. Translation providers do not generate the audio; Read Frog uses its Edge TTS voice configuration.
Voice mapping
Assign a voice to each language you regularly read. Read Frog chooses the mapping for the detected language and falls back to the default voice when no language-specific mapping exists.
Use the preview control before saving a mapping. Voice availability and quality can vary by language, operating environment, and the upstream speech service.
If mixed-language text sounds wrong, add explicit mappings for both languages instead of relying on one default voice.
Rate, pitch, and volume
All three controls accept integer values from -100 to 100; the default is 0.
| Control | Lower values | Higher values |
|---|---|---|
| Rate | slower speech | faster speech |
| Pitch | lower voice | higher voice |
| Volume | quieter | louder |
Start with small changes such as -10 or 10. Extreme combinations can sound unnatural or make speech difficult to understand.
Troubleshooting
- Speak is not visible: enable it under Options → Selection Toolbar.
- Wrong language voice: create a mapping for the detected language and preview it.
- No audio: confirm the tab and operating system are not muted, then try another voice.
- Speech is clipped or unstable: return rate, pitch, and volume to
0and test again. - Feature changes unexpectedly: remember that TTS is Public Beta; export your configuration before a large voice-mapping change.
Voice settings are included in configuration exports and backups. See Configuration, Sync & Backups for recovery options.
