EmotiVoice — A Multi-Voice and Emotionally Rich TTS Engine

Overview

EmotiVoice is a powerful, open-source text-to-speech engine that supports both English and Chinese languages with over 2000 different voices. Its unique selling point is the ability to synthesize speech with a wide range of emotions, making it a versatile tool for developers and content creators. The project offers an easy-to-use web interface and a scripting interface for batch processing, catering to various user needs.

Key Features

Emotional Synthesis: Create speech with a variety of emotions.
Multi-Language Support: Speaks both English and Chinese.
Over 2000 Voices: Extensive voice options for diverse applications.
Web and Scripting Interfaces: User-friendly for individual and batch processing.

Use Cases

Content Creators: Generate voiceovers with specific emotional tones for videos and podcasts.
Developers: Integrate emotional speech synthesis into applications for a more engaging user experience.
Enterprises: Use for customer service bots and interactive voice response systems with a human-like touch.

Advantages

Open-Source: Free to use and modify.
Emotional Range: Broad spectrum of emotional tones for more natural speech.

Limitations / Considerations

Requires NVidia GPU: For optimal performance, a machine with an NVidia GPU is necessary.
Limited Language Support: Currently supports English and Chinese, with plans to expand.

Mozilla TTS: An open-source text-to-speech system with a focus on high quality and fast synthesis, but without the emotional synthesis feature.
Tacotron 2: A text-to-speech synthesis model that offers high-quality audio but lacks the multi-voice and emotional range of EmotiVoice.
