haven VS TTS

I found this https://github.com/guardianproject/haven which has the right features but looks like the project is abandoned. The app can not be installed on my Pixel 7, is not supported.

Haven, available either on F-Droid or Google Play.

Haven might be what you are looking for. It can activate sound and video recording upon noise, light and vibration. It is in the IzzyOnDroid Repo or has its own repo. Check the project page: https://guardianproject.github.io/haven

How does this compare to https://guardianproject.github.io/haven

Even better is something like the Guardian Project's Haven(https://github.com/guardianproject/haven) which IIRC Snowden contributed to.

It's incredibly cost-effective to just buy an old Android phone (which comes integrated with multiple microphones, with good signal processing and noise cancellation), instead of building it with components.

Haven is specifically designed for intrusion detection, and for preventing people from tampering with your laptop for instance by detecting activity on the Android phone's sensors.

Adding to what the other commenter said, you may want to check this app: https://github.com/guardianproject/haven

Haven( GitHub ) from the guardian project: it's a good open-source motion detection app.

You could retire it to a personal surveillance camera with haven (needs a sim for registration though). With root, you could even set a charging limit so the battery doesn't die.

Fast or good, choose one

Mozilla's TTS is a python package installable with pip and uses cpu or gpu resources to render a choice of voices, they mostly sound natural and this is the good. https://github.com/mozilla/TTS

Mycroft's mimic3 is the default voice renderer for the Mycroft project that runs on pi hardware and sounds ok-ish, that is the fast. https://github.com/MycroftAI/mimic3

There are many others but these are the two I use according to if it needs to run on limited hardware or if the cycles fall freely from the sky.

Coqui-ai was a commercial continuation of Mozilla TTS and STT (https://github.com/mozilla/TTS).

At the time (2018-ish), it was really impressive for on-device voice synthesis (with a quality approaching the Google and Azure cloud-based voice synthesis options) and open source, so a lot of people in the FOSS community were hoping it could be used for a privacy-respecting home assistant, Linux speech synthesis that doesn't suck, etc.

After Mozilla abandoned the project, Coqui continued development and had some really impressive one-shot voice cloning, but pivoted to marketing speech synthesis for game developers. They were probably having trouble monetizing it, and it doesn't surprise me that they shut down.

An equivalent project that's still in active development and doing really well is Piper TTS (https://github.com/rhasspy/piper).

An RSS reader that integrates TTS (or TTS)

My solution would be to use a speech synthesis library, maybe eSpeak or Festival, just for ease of use; I think they each provide a library that you could use from C or C++ easily. This one from Mozilla is a more modern system with better-quality output, but it looks like it's set up to run through Python, and I haven't looked at it closely enough to see how much work it would be to get it working for you.

There is a lot of TTS and SST development going on (https://github.com/mozilla/TTS; https://github.com/mozilla/DeepSpeech; https://github.com/common-voice/common-voice). That is the only way they work: Contributions from the wild.

unfortunately not yet. I need to expand the library of languages and voices. looking around, it seems only Coqui had some traction re Brazilian Portuguese: https://github.com/mozilla/TTS/issues/160. If you foresee wide adoption of the tech for this locale, hit me up with DM

I haven't used it, but there's also mozilla/TTS.

Mozilla TTS

Instead, just use Firefox's open-source TTS model: https://github.com/mozilla/TTS
