If you working with machine learning and you need a dataset of voices, this app is for you.
Just start a server like these examples on your favorite cloud(gcp, aws, azure, etc) with a public url. It also works with localhost
# http upload
https://github.com/srJones1/nodejs-file-receiver-http
# socket
https://github.com/srJones1/nodejs-file-receiver-http
Configure the url in settings and record the voice.
A wav file will be uploaded to your own server.
