Text to speech (#5062)
* Add tts UI * Add tts backend * Add description to eleven labs credentials * Fix issue with fetching eleven labs voices * Fix issue with text to speech tab not showing correct saved voice * Add option to autoplay tts audio after prediction completes * Fix crash issue when first changing tts provider * Set up streaming response for text to speech audio * Update controllers - fix issue with sse client getting removed before tts events are sent * Use existing sse streamer to stream tts audio before sse client is removed * Add tts sse to redis publisher * Fix issues with TTS - openai voices, streaming audio, rate limiting, speed of speech * Refactor * Refactor TTS - fix issues with tts loading and stop audio buttons * Abort TTS SSE when clicking the stop button * Update SSE handling for TTS * Fix issue with test voice feature * Fix issue with tts voices not loading * Update generate tts endpoint and its usage in internal chat * Whitelist tts generate endpoint * Refactor Text-to-Speech Provider Selection and Enhance UI Components - Updated the text-to-speech controller to select the active provider based on status instead of the first available provider - Added audio waveform controls and test audio functionality in the TextToSpeech component, allowing users to play and pause test audio - Integrated Autocomplete for voice selection in the TextToSpeech component - Implemented TTS action management in ChatMessage to prevent auto-scrolling during TTS actions * - Implemented stopAllTTS function calls to halt existing TTS audio before playing new audio or starting a new TTS stream * Updated the condition for enabling TTS providers to exclude the 'none' provider, ensuring only valid providers are considered for text-to-speech functionality. * Remove unnecessary code * Add ability to abort audio streaming in TTS and release lock on chat input * Remove logger * Fix tts audio not playing when clicking speaker button * update * TTS abort controller * Fix abort not working for TTS autoplay * Send metadata event when aborting autoplay TTS * Fix UI issue * Remove elevenlabs sdk from root package.json * Remove redundant condition for tts autoplay in chatflow --------- Co-authored-by: Henry <hzj94@hotmail.com>
