TTSAutomate is a free, open-source Windows application designed to automatically convert bulk text into individual audio files. Developed by the community creator CaffeineAU, it is highly popular in the radio control (RC) hobbyist community for creating custom voice packs for RC transmitters. Core Functionality
Bulk Audio Generation: It takes a spreadsheet-like list of custom phrases and converts them into dozens of individual audio files simultaneously.
File Management: Users can assign specific filenames and folder structures to every text line. The app organizes the output audio into those exact directories automatically.
Multiple Formats: It exports natively to WAV and MP3 audio formats.
Audio Tagging: The software automatically embeds metadata tags into the output files, including the voice name, text phrase, and the engine used. Text-to-Speech Engines
TTSAutomate acts as a bridge to several online and offline speech generation systems:
Cloud Services: It connects with high-quality cloud platforms like Amazon Polly to access premium natural character voices.
Local SAPI Engines: It can leverage Microsoft Windows Text-to-Speech. If you select local Windows voices, the software can function entirely offline without an internet connection.
Language Support: It features built-in UI translations for English, French, Portuguese, German, Slovakian, and Czech, and fully supports accented characters for localized voice generation. Primary Use Case
The tool’s primary ecosystem is RC Transmitter Voice Packs. Radio controllers using open-source firmware like EdgeTX or OpenTX require very specific voice files to announce telemetry data (e.g., “Battery low,” “Flaps down”), switch positions, and flight modes. TTSAutomate makes updating or customising these thousands of required voice prompts incredibly quick.
You can download the software or review the documentation directly on the Official TTSAutomate Website or explore its source repository on GitHub.
