TTS Debug is a specialized tool designed for developers working on Chrome text-to-speech (TTS) extensions. This free add-on provides a robust test suite that ensures proper implementation of the TTS API. It features a combination of manual and automated tests, allowing developers to listen to audio outputs while also verifying callback timing information to confirm functionality. The tool is particularly useful for debugging and refining TTS applications, ensuring they meet the necessary standards and perform as expected.

As an open-source extension, TTS Debug promotes transparency and community collaboration. Developers can access the source code to understand its workings better and contribute to its improvement. This makes it an invaluable asset for anyone involved in creating TTS functionalities within Chrome, streamlining the development process and enhancing the quality of speech synthesis applications.
