What is the difference between .swf and .pvf?

Description: An SWF file is an animation created with Adobe Flash that can be played by Flash Player or with a web browser that has the Flash plugin installed. It may contain text, vector and raster graphics, and interactive content written in ActionScript.; 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.
