Introduction

🧢 CapSpeech comprises over 10 million machine-annotated audio-caption pairs and nearly 0.36 million human-annotated audio-caption pairs. CapSpeech provides a new benchmark including these tasks:

1. CapTTS: style-captioned TTS

2. CapTTS-SE: text-to-speech synthesis with sound effects

3. AccCapTTS: accent-captioned TTS

4. EmoCapTTS: emotion-captioned TTS

5. AgentTTS: text-to-speech synthesis for chat agent
