DivX to SPH Converter
Extract DivX audio as NIST SPHERE speech data online
Video to Speech Corpus
Extract dialogue and speech from DivX videos directly into SPHERE format — skipping manual steps when assembling research audio datasets.
NIST Compliant
Output SPH files follow the NIST SPHERE specification. Import directly into Kaldi, HTK, or other speech recognition training frameworks.
Runs in the Cloud
DivX audio extraction and SPH encoding happen on our servers. No local SPHERE toolkit or audio tools installation needed.
How to convert DIVX to SPH
Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page.
Choose sph or any other format you need as a result (more than 200 formats supported)
Let the file convert and you can download your sph file right afterwards

Frequently Asked Questions
SPH (SPHERE) is the NIST standard for speech research audio. Converting DivX audio to SPH prepares video dialogue for linguistic datasets.
Kaldi, HTK, Praat, and the NIST SPHERE toolkit all support SPH files. SOX can also handle this format for processing and conversion.
SPH stores PCM audio without compression. Speech extracted from DivX retains full quality — crucial for accurate research and training data.
Yes — SPH and NIST both refer to the SPHERE format standardized by the National Institute of Standards and Technology for speech audio.
Batch upload multiple DivX files and convert them all to SPH at once. This accelerates building speech corpora from video archives.
