About
Async is a developer-first AI voice platform, rooted in technology that powers Podcastle, offering premium text-to-speech and voice cloning via a simple, high-performance API. Developers gain access to broadcast-quality, natural-sounding voices with under-200 ms latency, and can create personalized voice clones using just a three-second audio sample. It supports streaming output so audio plays as it’s generated, and offers transparent usage-based billing with real-time daily stats and per-second cost control. Built to scale from prototypes to full production, Async makes advanced voice capabilities accessible to indie developers and enterprises alike, backed by the same trusted infrastructure that fueled Podcastle.

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.
