SPHERE Conversion Tools. Many LDC corpora contain speech files in NIST SPHERE format. The programs below convert SPHERE files to other formats. sph_convert_2.1. This program is suitable for Windows systems. It converts many files at once. Users may find the batch conversion simpler, but may also find that the program provides less flexibility ...

NIST researchers simulate “sun and rain” to determine if weathering causes polymer coatings to release the nanoparticles they contain into the environment. On the left, Li-Piin Sung places a commercially available polymer with silicon dioxide nanoparticles into a chamber of the NIST SPHERE, a device for accelerated weathering that in one day subjects samples to the …

Developed under the auspices of the NIST Coatings Service Life Prediction Consortium, the NIST 2 m integrating sphere provides a source of collimated ultraviolet radiation in the 290 nm to 400 nm region of the spectrum. Visible and infrared components of the input radiation are largely removed by dichroic mirrors or filters.

Audio is presented as 16 bit, 8kHz, NIST SPHERE format files. Accompanying reference files are divided by analytic tasks utilized in the OpenSAT Pilot and are UTF-8 encoded text or XML files. ASR and KWS scoring tools are also included. Samples. Please view the following samples: Audio Sample (SPH) Transcript Sample (TXT) STM Sample (TXT)

Audio data distributed by the Linguistic Data Consortium (LDC) is typicaly distributed on CDROM using the NIST SPHERE format. A SPHERE file consists of a single fixed size header followed by binary audio data. The header is organized as name value pairs in a 1024-byte blocked, ASCII structure placed at the beginning of the file. ...

NIST provides software to manipulate SPHERE audio files. Some users who may not have a UNIX system (or wish to do things that the NIST utilities cannot do) may want SPHERE files in another format. LDC provides two simple, stand-alone programs that will convert SPHERE speech files to other formats, particularly MS WAV or header-less (raw) format.
