Soon you'll also be able to do speech to text locally, as Apple is adding a SpeechAnalyzer API [0] which is apparently faster than whisper [1].

I love projects like this, doing things because you can. Especially low power, off-grid projects.

However I did not love the writing style of this article. Lots of repetition. Asking questions to stress a funny point. Lots of repetition.

I don't mean to sound like a jerk, even though I've succeeded at it. The author is cool, what they did is just as cool.

I see your fruitPhone 8 and raise my Motorola MB525 'Defy', Motorola MB526 'Defy+' and Samsung J3 which are in use as Wifi-enabled trailer camera. The phones provide a Wifi hotspot through which the camera's images are accessed. Hook up the trailer, connect to the Wifi network and voila, you can see what's happening in the trailer behind you. The oldest device in this list is from 2010, all of them run either Cyanogenmod (MB525 and MB526) or its successor LineageOS (J3). I replaced the batteries in the Motorola's, the J3 runs on its original battery. Oh, all of them run without a screen since that is not visible anyway and was broken in 2 of the 3. Android runs just fine without a screen and using the things this way takes a little less power.

The MacStories article made it seem about 2x as fast as Whisper, but there's no network or shared servers involved, so it's effectively faster.

HomePods perform real-time vision processing on multiple camera streams for HomeKit. However, the primary quality challenge lies in the video quality of HomeKit-enabled doorbell cameras that can consistently stream to Wi-Fi. For instance, my doorbell operates on 2.4 GHz Wi-Fi, resulting in highly compressed video streams. This compression likely impacts the results.
