From a66b2f03742bf8a6e5c63d4b21dc1e21f7e7cdf2 Mon Sep 17 00:00:00 2001 From: Rahul Vadisetty Date: Fri, 23 Aug 2024 11:10:56 +0500 Subject: [PATCH] meta-ai-voice-enhancement.py This commit introduces several key enhancements to the MetaVoice-1B text-to-speech (TTS) model, focusing on improving AI capabilities and user interaction: Advanced Speech Parameters: Added functionality for dynamic adjustment of speech stability and speaker similarity. Users can now fine-tune the top_p (speech stability) and guidance (speaker similarity) parameters through sliders, allowing for more personalized and controlled speech output. Enhanced Voice Cloning: Improved handling of uploaded voice samples for cloning. The script now includes validation for file size and duration, ensuring that uploaded samples are suitable for high-quality voice synthesis. Samples must be between 30-90 seconds and less than 50MB to ensure optimal performance. User Interface Improvements: Updated the user interface to provide a more intuitive experience. Users can choose between preset voices and uploaded target voices, with automatic layout adjustments based on the selected option. The interface now features clear labels and better organization for ease of use. Robust Error Handling: Enhanced error handling to manage edge cases and provide informative feedback. The script includes comprehensive checks and error messages for input validation, such as handling text length limits and ensuring uploaded files meet the required criteria. These updates aim to enhance the functionality, usability, and robustness of the MetaVoice-1B TTS model, delivering a more versatile and user-friendly text-to-speech solution.
