Products that do what Tortoise TTS as an at-cost open-source pay-per-second API does
Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements…

I built Whispering because I believe transcription is too fundamental a tool to be locked behind paywalls. It's a cross-platform desktop and web transcription app that turns speech into text with a keyboard shortcut, among other things. The app lets you bring your own API key (OpenAI, Groq, etc.) and make direct calls. If you want complete privacy, it also supports local transcription. Either way, your audio never goes through any middleman servers. It's super lightweight (~22MB), built with Svelte 5 and Tauri, and works on Mac, Windows, and Linux. I've been using it daily for the past few…

I built a simple text-to-speech converter at texttospeech.site Free tier: 10 generations/day, standard voices, no account needed. Pro tier: Neural2 voices, 2000 chars, downloadable MP3s. Stack: Next.js, Google Cloud TTS API, Vercel. The $2 domain was an SEO experiment after my speechtotext.xyz satellite drove 22% of traffic to my main product. Curious if exact-match keyword domains still work for TTS searches. Feedback welcome — especially on voice quality and UX.
