Speech Quality Estimation

     Posted on: 2018-04-02

Speech Quality Estimation (SQE) is a language-, domain- and channel-independent technology that quantifies the quality of an audio recording. 2 most important statistics used in the calculation of the SQE score are SNR (signal-to-noise ratio) and the bitrate of the recording. SQE is usually part of the rapid filtration process in deployments. SQE also measures over 20 other properties of the recording, all of which can be found in the output file and further processed. See description in SPE documentation. Typical use cases are: verification of recording quality on the input, searching based on quality of the recording, noise of…

Prefiltering

Prefiltering is a very important part of basically any speech technology architecture. These 2 technologies are very fast and can significantly decrease the load and increase the precision of the following technologies (the exact number depends on the type of your data), thanks to sorting out the files with unacceptable quality or not enough net speech. The 2 technologies in question are Speech Quality Estimation (SQE) and Voice Activity Detection (VAD).

Sizing of the computing units for speech technologies

     Posted on: 2018-02-02

Best practices for good sizing of Phonexia technologies depend on a few facts: Intense work with large data sets requires good performance and bandwidth between RAM and CPU. It all depends on the size of the files with technological models data, usually loaded into RAM and used intensively for computing operations Always think only about physical cores of CPU (HT, VT features can't help in performance) Also seek for CPUs with a large L3 cache. And the better CPUs are those with higher l3_cache_size/#_of_physical_CPU_cores ratio. We currently assume that CPUs from the current Intel Xeon Family in the 4th generation…
