Description

RalfHerzog post:

This is a good idea to implement FLAC into the VoxForge? speech submission application.

Maybe you're interested to know my experiences with FLAC. When I record 99 sentences, the corresponding wav files consume about 50 megabytes. When I compress them with flac-1.2.1b.exe, the files consume less than 20 megabytes.

I would estimate that you need about five megabytes when you upload ten sentences via the VoxForge? speech submission application. Using FLAC you would need just about two megabytes.
