Does Huawei matebooke need to use speech-to-text when networking?

No need. Voice input is the function of the notebook itself, which has nothing to do with the network. When you enter text in Huawei matebooke, you can also enter voice and text normally without networking, but if you want to transmit the input text to others, you need networking. When you turn on the voice input of your laptop normally, you can use the voice input function when you are not connected to the internet, but if you are not connected to the internet, the text you entered will not be transmitted.
