Simple browser voice recorder.
Publish code to a server with PHP (tested with version 7). Runtime (PHP server user) must have rights for writing to the falder data/.
Also, modern browsers block MediaStream Recording API (required for recording) unless the communication is over HTTPS/TLS.
For security, whole site should be protected with .htpasswd. Use for example this tool to generate .htpasswd file with usernames and passwords.
Publish dataset(s) to the folder datasets/. A dataset is a file with a sentence/paragraph per line. User is presented each time with a random line (sentence/paragraph) from the given dataset.
Recordings are stored in folder data/. For each user is created a new folder here. Each recording has name in format dataset-line_id[_duplications].ogg.
Each user should enter his/her name or ID (to resume work for example), by default there is a random string generated.
