Is "paste your OpenAI API key" the new form of "paste your credit card number with exp/code" for example, to check if its been compromised?
yohannparis 55 minutes ago [-]
You can generate a specific API key, and make sure to monitor it by setting a budget limit to it.
They should explain this to people in their form to avoid people pasting their main key.

You don't even need that. Just paste your pdf in codex or the gpt work app and say make me an audio book from this with such and such kind of voice.

There was a guy who made a "has your SSH key been compromised? Paste your private key here" website as a joke, which lasted about a week until his low budget host killed it.
I love using https://convert.to.it/ for all of my converting needs; everything is client-side in the browser with over 400 file extension options to choose from.
I did something very similar to this, for myself, but which takes a web page for an article, cleans up the text to preserve the article only, and converts it using TTS, then adds it to a cloud bucket with an RSS stream, and I use that RSS link as a podcast in Apple Podcast.

I do similar things, just use ElevenLabs for tts - a good selection of voices.
A good protip - tell an agent to rewrite the article slightly for better listening flow. Some subtle changes in sentence structure etc can make listening way more pleasant.
I use the TTS on Google Cloud. It's effectively free.

What TTS do you use? I find the OpenAI ones really unpleasant to listen to and elevenlabs is better but still not quite right somehow.

What about license of such output? Won't Google and OpenAI be coming to my door for their share from the sales of "my" audiobooks?
sureMan6 2 minutes ago [-]
You'll have to read the license agreement for openAI or Google on their tts
Or look into open source tts models with liberal commercial licenses
Generally I'd stay away from the site/project/repo in the OP and just do your own research on this (because the OP site is vibe coded in a sleazy way that's unnecessarily used car salesman-y and doesn't offer anything you couldn't just do better yourself with one codex or chatgpt prompt)
Edit: to be clear there's a lot of different tts providers, they probably all offer tts you can use commercially, you can look at benchmarks for the providers and then the specific TOS

Please share an example of a two-speaker podcast that it has generated, add support for spoken Thai, and I will pay & use it weekly.
janpmz 33 minutes ago [-]
Here you go my friend, a two speaker podcast in Thai :)
How well does it handle pronunciation, especially of things like proper nouns? This has been one of the harder parts I've found. On a financial web site I saw one example where the generated audio pronounced initiates as a noun instead of a verb. It's a subtle difference but can significantly change the meaning if worded wrong.
I was trying to use TTS to regenerate some old audiobooks and getting names pronounced correctly is pretty hard unless the model supports something like SSML.

This trend to sell subscription with a price for "credits".
For a wrapper around costly LLM providers.
For a result one could get with voicebox for free.
amaldavid 2 hours ago [-]
It was always harder to get it to sound right, I had built Lissin around this thesis itself. You can throw in a PDF or a link and can get a podcast, deepdive or just narration with different voices in Lissin.
For those interested in better voices, you can try and let me know.
If someone sends me AI generated audio they're reccomending, I from then on out see them differently and not in a good way. I dont even want to read the outputs of an LLM let alone listen to them. Wild.

Let me guess, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs and then use SVN or CVS on the mounted filesystem?
Yes, because these days the world has changed since then.

> Use the AI you already pay for
I thought this would mean I could use my subscription, as OpenAI/Codex supports this kind of authentication flow, and it's very easy to integrate with that as a service, and users login with the OpenAI authentication flow, or via device codes.
Instead this asks for an API key, which is very different from "Use your OpenAI subscription" and to be honest, I'm not sure how anyone who has a OpenAI subscription could mistake this for such. Has this even been tested once?
Maybe I missed something obvious, I had a five second look and closed it when it seemed to be outright intentionally misleading.

The title is misleading - should be "Use your openai subscription AND a TTS api key"
Much less interesting.
janpmz 4 hours ago [-]
There are two parts to the processing. The processing of the document itself is done on your OpenAI/Codex subscription. Additionally, you have to submit an API key for the text-to-speech processing. There you can use a Gemini key or an OpenAI key.

Thanks! Currently, I'm using Gemini TTS and Kokoro TTS as a free option. Kokoro is fast and I can run it on my own server, but I'm not using it as a standard yet because Gemini supports more languages and has more voices available. But text-to-speech processing is the biggest bottleneck at the moment.

What prevents someone submitting an epub or a pdf and ask claude or another llm to narrate a novel in morgan freeman's voice?
AbsurdCensor 4 hours ago [-]
At home this is super easy, use one of the multiple TTS models out there and provide a clean clip of Morgan Freeman's voice. Typically around 10 seconds will do. I just run a python script to daily scan my FreshRSS sources, compile my news and generate a 'podcast' that's about 10 minutes for a morning listen. Currently using F5-TTS, but there are lot's of other models out there as well.

Claude has gotten pretty sensitive to copyright. In addition to the no song lyrics that was posted in another article, I also find it will not generally transcribe podcasts (you have to play with model versions and even effort inside that).

It handles the formatting of scientific papers very well. E.g. I can exclude footnotes etc. But I didn't test it much with tables yet.
flatline 1 hours ago [-]
I went the route of handling epub first (really, anything pandoc can convert to epub) on ebookaloud, and it took quite a few iterations to get consistent parsing across a wide corpus of test documents.
My experience is that gathering and testing with that corpus was about 30% of the overall effort. I have not yet gathered the motivation to tackle pdf: it’s more of a layout format than a text format. Not just tables but multi-column layouts and similar oddities leave a pile of imperfect heuristics in their wake.
Multi-lingual support is even worse. I was working with arabic script in pdf years ago and they don’t even capture the encoded text, just rendering instructions due to the high number of ligatures. I don’t know if things have improved since then.
