SPH is a format used in speech processing research, especially by the National Institute of Standards and Technology (NIST). It stores mono audio data, often used in language and speech recognition datasets. SPH is primarily handled in academic and scientific software.
WAV is an audio format developed by Microsoft and IBM for storing uncompressed audio data. It’s widely used for high-quality audio recording and editing. WAV files offer excellent sound fidelity and are compatible with nearly all audio software and hardware.
