Show HN: Voice-Pro – AI Voice Cloning Magic: Transform Any Voice in 15 Seconds
It's really easy for a technical person to do as well.
I use Coqui TTS[0] as part of my home automation, I wrote a small python script that lets me upload a voice clip for it to clone after I got the idea from HeyWillow[1], and a small shim that lets me send the output to a Home Assistant media player instead of using their standard output device. I run the TTS container on a VM with a Tesla P4 (~£100 to buy) and get about 1x-2x (roughly the same time it'd take to say it, to process) using the large model.
Just for a giggle, I uploaded a few 3s-5s second clip of myself speaking and cloned my voice, then executed a command to our living room media player to call my wife into the room; from another room, she was 100% convinced it was myself speaking words I'd never spoken.
I tried playing with a variety of sentences for a few hours and overall, it sounded almost exactly like me, to me, with the exception of some "attitude" and "intonation" I know I wouldn't use in my speech. I didn't notice much of an improvement using much longer clips; the short ones were "good enough".
Tangentially, it really bugs me that most phone providers in the UK insist you record a "personal greeting" now before they'll let you check your voice mail box, I just record silence, because the last thing I want/need is a voicemail greeting in my voice confirming to some randomer I didn't want calling me, who I am and that my number is active, even more so knowing how I can

Show HN: Offline audiobook from any format with one CLI command
For anyone who is interested, CoquiTTS (formerly, MozillaTTS) was great, but the project isn't maintained anymore (athough there's been some confusion about whether or not it's active. See: https://github.com/coqui-ai/TTS/issues/4022).
Looks like there's an effort to keep an actively maintained fork here, though: https://github.com/idiap/coqui-ai-TTS

Ask HN: What is the state of OSS voice cloning?
I am super impressed by the quality of voice cloning offered by Eleven Labs and Play.ai. I feel like I see impressive OSS demos on social frequently, but last weekend I took a few popular ones for a spin and quality wasn't even close to the proprietary models.

When I did a similar thing (but with less LLM) I liked https://github.com/coqui-ai/TTS but back then I needed to cut out the conversion step from tensor to a list of numbers to make it work really nicely.

Ask HN: Open-source, local Text-to-Speech (TTS) generators
I just noticed that https://coqui.ai/ is "Shutting down".
I'm building a web app (React / Django) which takes a list of affirmations & goals (in Markdown files), puts them into a database (SQlite), and uses voice synthesis to create voice audio files of the phrases. These are combined with a relaxed backing track (ffmpeg), made into playlists of 10-20 phrases (randomly sampled, or according to a theme: "mind" "body" "soul") and then play automatically in the morning & evening (cron). This allows you to persistently hear & vocalize your own goals & good vibes over time.
I had been planning to use Coqui TTS as the local text-to-speech engine, but with this cancellation, I'd love to hear from the community what is a great open-source, local text-to-speech engine?
Generally, I learn both the highest quality commercially available technology (example: ElevenLabs), and also the best open-source equivalent. Would love to hear suggestions & perspectives on this. What voice synth tools are you investing your time into learning & building with?
