24 alternatives to bullfrog, a text-to-speech service
Hi all! I created a text-to-speech service called bullfrog. I am aiming to create a simple, inexpensive TTS service that can be called from any application. We currently have a ruby gem, and plan to add a PHP library and many others as well. Would love your feedback and criticism! https://bullfrog.io

Inworld TTSfree tier, from $25/mo▲318Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we're releasing today in public preview. We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I/O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models. Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as graphs. For instance, a basic voice-to-voice…

Welcome to Project S.A.T.U.R.D.A.Y. This is a project that allows anyone to easily build their own self-hosted J.A.R.V.I.S-like voice assistant. In my mind vocal computing is the future of human-computer interaction and by open sourcing this code I hope to expedite us on that path. I have had a blast working on this so far and I'm excited to continue to build with it. It uses whisper.cpp [1], Coqui TTS [2] and OpenAI [3] to do speech-to-text, text-to-text and text-to-speech inference all 100% locally (except for text-to-text). In the future I plan to swap out OpenAI for llama.cpp [4]. It is…

Hi HN, I made a simple web tool called SonicFlow (https://voice.clevermock.com) for converting text to an MP3. I've used other TTS tools, but was looking for something with zero friction - no sign-up, no feature-gating, no complicated SSML tags to learn. Just a text box and a download button. So I built it. It's a clean front-end that pipes text to a TTS model and serves the audio file directly. Useful for quickly listening to articles, comments, or maybe generating placeholder audio for a project. It's free. Hope it's useful. Feedback is welcome.
