What about the TTS engine? Should have explained it too.

[@amirnasser7768]

Great video, just a small correction when you explained the spectrogram you mentioned that brighter areas signify high frequency and darker ones signify low frequencies. The brightness, in general, corresponds to the energy "loudness" at a particular time for a particular frequency. So you can have low frequency with high energy.

[@Acadaimy]

Good point! Thanks for your note - appreciate for taking the time!

[@kartikpodugu]

Exactly brother. I was about to write about it and felt very happy seeing your comment.

[@vincmp]

Speech recognition typically converts speech to text, which is important for dictation, transcription, and other applications that need text input. It employs natural language processing (NLP) algorithms to comprehend human language and reply in a manner similar to that of a person.

I own Amazon echo, Alexa is great virtual assistant to chat with she understands me well, but now I know her as well because of you,thanks

[@Acadaimy]

Glad you find the video useful!

[@marcelbritsch5127]

I'm wondering whether there is a minor mistake in the explanation of the spectrogram. She says "the bright areas signify high frequencies" but frequency is plotted vertically. The colour indicates amplitude (volume) as per the key to the far right.
Happy to be corrected if I got that wrong.

[@huongq123]

This is one of the best channels I've seen about AI technology. I have learned a lot from this video. thank you for sharing. very helpful video

[@Acadaimy]

So glad you found the video useful!

[@rafayhashmi3337]

@2:37 areas that are brighter indicate more amount(amplitude) of those frequencies, and that of darker ones show less amount(amplitude) of those frequencies , great explanation though.

[@Acadaimy]

Thanks, appreciate your feedback!

[@midiness]

So in the 3rd stage they used single intent recognition to understand our command and execute them later. I had some idea like that before and now everything make sense.

[@Acadaimy]

So glad you found the video helpful!

[@rikimaruazuma1450]
