Frequently Asked Questions
SPH (SPHERE) is the NIST standard for speech research corpora. Convert when building speech datasets or feeding audio into recognition systems that expect this format.
Kaldi, HTK, NIST SPeech HEader tools, SoX, and Audacity can process SPH files. It is widely used in computational linguistics and speech science.
Yes — SPHERE headers carry rich metadata including speaker info, recording conditions, and channel data. This metadata is valuable for speech research.
SPH is designed for speech corpora — typically mono, 16 kHz, 16-bit. While it can hold music, its metadata structure is built for spoken language data.
Yes — convert MOV interview or lecture recordings to SPH for inclusion in speech recognition training sets and linguistic research corpora.
