Voicetrell: Text to Speech

Shape a short narration using ordinary speech voices installed on your device. Voicetrell keeps editable script projects locally and turns their segments into a WAV audio file. Split a script into segments, edit the spoken spelling separately from the written text, choose an available offline voice and speech rate, and set pauses between segments. Preview a segment, render the script, listen to the result and share the WAV file. Scripts and spoken overrides each support up to 10,000 characters, with at most 50 segments and 1,600 characters per segment or override. Pauses range from 0 to 3,000 milliseconds and speech rate from 0.6 to 1.4 times normal. Joined WAV output is limited to 30 minutes; shorter scripts may also reach the device tool's audio-size limit. Voice names, languages and availability depend on the installed system speech engine. An installed offline voice is required for rendering. Personal Voice, voice cloning and network voices are outside this app's scope. Check the voice engine's terms before commercial use; the app does not grant commercial rights to system voices. Scripts are not uploaded to a speech service. No microphone recording, account, advertising, subscription or in-app purchase is required. The interface is in English.
