NIST files are sound recordings stored in the National Institute of Standards and Technology's Speech Header Resources Exchange Format (SPHERE), designed for speech recognition software like Hidden Markov Model Toolkit. NIST files consist of both metadata information as well as audio data in waveform format; VLC can playback these files while soX or FFmpeg may convert them to more common audio file types such as WAV for conversion purposes.
Upload a file, click "Convert", and use additional options to quickly modify its contents before downloading the final NIST file after processing has completed.
Our NIST converter works on Windows, Mac OS, Linux, iOS and Android systems alike - our servers automatically process each file without requiring you to install plug-ins or applications!
We guarantee 100% of the privacy and have no access to your files once uploaded/converted, making them inaccessible by anyone and completely protecting them.
