Hi, I built the client UI for this and... yea, I really wanted to get Firefox working :(

We needed a way to measure voice-to-voice latency from the end-user's perspective, and found Silero voice activity detection (https://github.com/snakers4/silero-vad) to be the most reliable at detecting when the user has stopped speaking, so we can start the timer (and stop it again when audio is received from the bot.)

Silero runs via onnx-runtime (with wasm). Whilst it sort-of-kinda works in Firefox, the VAD seems to misfire more than it should, causing the latency numbers to be somewhat absurd. I really want to get it working though! I'm still trying.

The code for the UI VAD is here: https://github.com/pipecat-ai/web-client-ui/tree/main/src/va...

Do you know why there's a difference in the performance of the algorithm in another browser? I would expect that all browsers run the code exactly the same way.

Do not go by the warning message. It does work just fine on Firefox latest. Cool, demo, btw!

I hate that everyone just develops for chromium only

This site works fine in safari/mobile safari, it is not ‘chromium only’

WebKit and its derivatives then.

I tried it with FIrefox 127 (production) and it worked just fine for me even though there is a huge banner on the top.

They're not necessarily standards. I clicked on the first negative one and it said draft.

One browser vendor proposing things other vendor NAKing it makes it a vendor-specific feature. Like IE had its own features.

Yeah but we’re trying to fight against browser engine superiority, aren’t we?

I hate using chrome, but I’m forced to with any application that uses we busb/web serial or Bluetooth.

But that's basically complaining that firefox doesn't just blindly adopt whatever google proposes. A lot of the concerns are about security and privacy, the thing that mozilla is praised for doing better than google.

And no, you're not forced to use google. You can make native applications when it's necessary to use privileged interfaces.

That's a fair argument, but IMO Mozilla is dogmatic to a point it'll be detrimental to them long-term.

You prefer the management of Chromium, which makes billions a year from invading your privacy and force feeding you advertising, while also ruining the internet ecosystem?

Yes, me lightly criticizing Mozilla means that I endorse Google. Fuck off

Likely a lot of people on HN use Firefox

It is working perfectly for me on Firefox (version 127).

Thanks for sharing. I did make some changes that seems to have improved things, although I do still see the occasional misfire. Perhaps good enough to remove that ugly red banner though!
