About
CosyVoice is Qwen Cloud’s voice cloning and speech synthesis model in the CosyVoice series, designed for professional text-to-speech scenarios with improved sound quality, naturalness, expressiveness, and cloning fidelity. With a short reference recording, it can create a highly similar custom voice without model training; Qwen recommends 10–20 seconds of clear speech, while at least five seconds of continuous speech is required. The model supports real-time, streaming text-to-speech synthesis, allowing applications to accept text and return audio with low first-packet latency. It supports Chinese, English, French, German, Japanese, Korean, and Russian for cloned voices, with language hints available to improve identification during enrollment. Source recordings can use WAV, MP3, or M4A formats and should contain clean speech without background music, noise, or additional speakers.

About
NVIDIA Parakeet-RNNT-1.1B is a multilingual automatic speech recognition model built for quality transcription across voice applications. With 1.1 billion parameters and training on more than 90,000 hours of speech, it supports 25 languages and regional variants, including English, Spanish, French, German, Italian, Arabic, Japanese, Korean, Portuguese, Russian, Hindi, Dutch, Danish, Norwegian, Czech, Polish, Swedish, Thai, Turkish, and Hebrew. The model automatically detects the spoken language and uses a universal tokenizer created by training language-specific tokenizers and merging them into a shared vocabulary, enabling efficient cross-lingual learning and deployment. Parakeet-RNNT produces case-sensitive transcripts with upper and lowercase text, punctuation, spaces, and apostrophes, making the output suitable for production voice applications and downstream language understanding.
