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
VoiSpark is a browser-based AI voice generation platform that transforms text into natural, human-like speech across 30+ languages and dialects, offering over 100 voice templates spanning ages, accents, and personas. It supports real-time streaming with open source models like Nari Labs Dia and premium engines such as ElevenLabs, all accessible via a simple web interface or REST API. Users can fine-tune voice characteristics through intuitive sliders and context-aware generation that adapts pacing and tone to any script. Instant 30-second previews let you sample voices risk-free, while multi-format flexibility enables text input via typing, PDF uploads, or Google Docs syncing and exports as MP3 or WAV for seamless editing. Advanced features include voice cloning from short samples, switchable "professional” and “expressive” models for clarity or creativity, and batch generation for podcasts, e-learning, audiobooks, video dubbing, social media clips, and game character voices.
