About this app

TGSpeechBox — Fast, formant Text-to-Speech
TGSpeechBox is a free, open-source text-to-speech engine that runs entirely on your device. No internet connection
required. No data collected. Just speech. It may sound like something from the 90s, but this is precisely what the brain needs to listen to speech at fast rates.
Use it two ways:
- Standalone app: Open TGSpeechBox, type or paste text, and tap Speak. Adjust speed, pitch, language, and voice to
your liking.
- System TTS engine: Set TGSpeechBox as your default text-to-speech engine in Android Settings. Screen readers like
TalkBack, apps, and the system will use it automatically.
Features
- 26 languages including English (US, UK, Canadian), Spanish, Mexican Spanish, French, German, Italian, Portuguese
(Brazilian, European), Dutch, Danish, Swedish, Polish, Czech, Slovak, Bulgarian, Croatian, Romanian, Russian,
Ukrainian, Hungarian, Finnish, and Chinese (Mandarin)
- 5 distinct voice presets
- Adjustable speech rate (0.3x to 3.0x) and pitch (40–300 Hz)
- Choose which languages appear in your system TTS language list
- Fully accessible with TalkBack

Privacy first

TGSpeechBox makes zero network connections. All speech synthesis happens on your device. No analytics, no tracking, no
accounts.
