Show HN: OfflineTTS — Free browser-based TTS & STT that runs locally (offlinetts.com)

OfflineTTS has launched a free, browser-based toolkit that combines various AI audio capabilities, including text-to-speech (TTS), speech-to-text (STT), subtitle generation, and audio conversion for documents like EPUBs and PDFs. This comprehensive platform operates locally, allowing users to keep their files private while leveraging local TTS engines designed for enhanced performance across different languages and file types. Notably, the toolkit supports 99 languages for STT and facilitates audio exports in formats like WAV and MP3, enabling creators and researchers to efficiently generate audio content. This initiative is significant for the AI/ML community as it prioritizes privacy and accessibility, allowing users to conduct tasks without relying on cloud services. With offline functionality for certain processes, users can transcribe audio, create subtitles, and convert text to speech without data exposure to third-party servers. The inclusion of multiple local TTS engines like Kokoro and Whisper enhances the versatility of audio generation, catering to diverse needs such as content creation, accessibility, and academic study. Overall, OfflineTTS represents an innovative step toward personal and responsible use of AI audio technologies.
