thank you!

prompt engineering is a thing, and it's not a thing that you get on social media posts with emojis or multiple images.

is it a public-facing product?

picovoice processes on the device and you can fine-tune the models https://picovoice.ai/platform/cat/
if you're running it locally, they don't and cannot.

if you're using the hosted whisper, they can. however, they don't specifically talk about it.

I didnt disclose as I was not gonna promote anything, but I work for a startup specializing in on-device voice recognition. I am 100% biased towards on-device voice processing :)

i just wanted to share my 2 cents, as it's not unique to Apple and the cloud can be costly even if you own it. Big tech has been investing in on-device for a while. besides voice commands, apple and google do transcription locally too. because now you can have local speech to text with cloud level accuracy and of all the reasons you shared - cost, privacy, latency etc. (but again, i'm biased)

Amazon has been working on on-device voice for a while. Actually everyone is trying to do that. Running large speech models in the cloud is expensive, considering the number of devices, they probably need more than "surplus" :)

Re:Python Tutorial: Creating video subtitles on Wednesday August 31, 2022 @03:04PM (#32666871)
Tutorial on adding subtitles to videos using the Picovoice Leopard Speech-to-Text Python SDK.

1. Install the software 2. Run the code to convert video to text 3. Create an SRT (SubRip subtitle) file

Example: Adding subtitles to a video on YouTube with pytube.

This tutorial requires Picovoice Console account- free to create, allows free transcription for up to 100 hours/month. Processes voice data locally on the device.

here's the accuracy and cost comparisons: https://picovoice.ai/platform/cat/
