What is a SPH file?
SPH is a file format used to store speech data, often in conjunction with the SPHERE header developed by the National Institute of Standards and Technology (NIST). It's commonly used in speech research and linguistic studies.
SPH files usually contain uncompressed PCM audio and can be found in academic speech corpora like TIMIT and Switchboard.
How to open SPH files
SPH files can be opened with SoX, Audacity (with plugin), and NIST’s own SPHERE tools. They are common in speech databases and research projects.
To share or play them easily, convert SPH to WAV or MP3 using AnyConv online.
