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

Elmren Voice is a local text-to-speech studio for Mac (macOS 13+, Apple silicon). It turns reading homework into a read-along page where each word lights up as it's read — narrated by one of 63 built-in voices or a clone of a parent's own voice from a 10-second recording. Exports include audio files, chaptered M4B audiobooks, karaoke-style MP4 videos, and the word-highlighted read-along page as a single HTML file that opens in any browser. All synthesis runs on-device: text, recordings, and audio never leave the machine. One-time purchase of $39.99, no subscription. Typical users: parents of dyslexic and emerging readers (read-aloud fluency practice), homeschool families, and anyone who wants offline TTS with private voice cloning.
