Unless something has changed, it did. The page linked reads:
And, obviously, this POC is open source, the code is publish here on our forge.
The link takes you to their repos. The server repo has instructions on self-hosting directly on your server or with Docker. The app repo has code for both the iOS and Android apps. That’s good, because the iOS app at least doesn’t have a built-in way to select a different backend server.
Whisper is by OpenAI and as far as I know they have not shared the training code, much less the data sets, so the best you can do is fine-tune the models they’ve provided.
If use of Whisper is a problem, but the project is otherwise interesting to you, you could ask them to consider using a different STT solution (or allowing the user to choose between different options). I’m not aware of any fully open STT applications that are considered to be as capable as Whisper, but if you do, that would be great info to share with them.
No. Trickle down economics refers to things that benefit the wealthy (mostly government policies, particularly related to taxes and subsidies) that will allegedly benefit everyone by “trickling down.” Supply-side economics are an example of trickle-down economics. Trickle-down economic policies have been shown to effectively increase income inequality and studies suggest a link between them and reduced overall growth.
Giving the wealthy tax breaks in the hopes that they’ll spend the extra money they have available on security details, on the other hand, would be an example of trickle down economics.
