ParrotSpeech TTS: Hybrid Autoregressive and Flow-Matching Text-to-Speech

ParrotSpeech TTS is a sophisticated multilingual text-to-speech system capable of reproducing high-quality speech with just three seconds of reference audio. The model utilizes a hybrid architecture that generates automatically recursive semantic tokens while employing stream-matching transducers to produce detailed audio tokens. This process is supported by the ParrotSpeech Codec, a specialized encoder that efficiently compresses audio into an arithmetic representation by combining vector and scalar quantization. Human evaluations show that the system significantly outperforms commercial competitors like ElevenLabs in terms of naturalness and speaker similarity across nine different languages. To further enhance performance, the developers employed Direct Priority Optimization (DPO) to fine-tune both discrete and continuous generation stages. Furthermore, the software framework is optimized for low-latency streaming via vLLM-Omni, utilizing CUDA graph acceleration capabilities to ensure rapid, real-time speech synthesis.

ParrotSpeech：打造语音领域的“Stripe" - 面向下一代语音代理的超低成本文本转语音基础设施
ParrotSpeech 推出语音条带 (The Stripe of Voice)，这是一款旨在使语音合成像现代支付系统一样经济实惠且可扩展的文本转语音基础设施。其目标是以超低成本提供高质量的文本转语音服务，接近 Discord 或 Google Translate 的免费使用水平。
其关键突破在于采用 CPU 优先的文本转语音技术，并结合分布式服务器-客户端架构，从而消除对昂贵 GPU 的依赖。在文本转语音行业面临 GPU 成本上涨、CPU 与 GPU 价格差距扩大以及经济可扩展性差等诸多制约因素的当下，语音条带从根本上重塑了成本模式。
