What is the difference between .pvf and .ogg?

Description: The Portable Voice Format (PVF) is a digital audio file format primarily used for storing voice recordings. PVF files are designed to encapsulate voice data at various bit rates, making them suitable for applications where voice clarity and file size are critical, such as voicemail systems, interactive voice response systems, and other telephony applications. Unlike more common audio formats that aim for high fidelity and music playback, PVF focuses on the efficient encoding of speech, optimizing for intelligibility and compact file size.; An OGG file is a compressed audio file that uses free, unpatented Ogg Vorbis audio compression. It is similar to an .MP3 file, but sounds better than an MP3 file of equal size, and may include song metadata, such as artist information and track data. OGG files are supported by many software music players and some portable music players.
