The server.technology_multithread_initialization setting in SPE configuration allows SPE to initialize instances of technologies during startup using multiple parallel threads. Default setting is OFF, i.e. instances of technologies are initialized using single thread, one-by-one. This allows easier tracking of eventual issues during SPE startup and better readability of technologies initialization log messages (only single initialization happens at a time). The downside…

…of speech technologies (precision of speaker identification, transcription accuracy, etc.). Therefore it is essential to have as clean audio as possible. ? DO’S ? DON’TS Capture the sound as close to the source as possible, i.e. as close to the speaker’s mouth as possible as close to the recording source as possible to minimize the amount of ambient sounds and…
A: Signal-to-Noise Ratio (SNR) is an important metric of whether a recording is worth further processing by other speech technologies, so it is part of our Speech Quality Estimation. However, calculating SNR automatically is not a trivial task. We use the fact that the statistical distribution of the frequencies in the waveform of speech has Gamma distribution. In contrast, noise…
…the processing, to check if the utterance maybe continues“. Decreasing this value means that even shorter pauses between words are detected as end of the segment. And vice versa – increasing this value means that longer pauses between words are not identified as end of a sentence. Speech threshold is a unitless value specifying threshold between silence and speech. Default…
…software cannot remove unwanted speech or music in the background. Denoiser is used to remove noise from the recording and at the same time to amplify the speech signal for: Better intelligibility when listening by people (recommended use), Achieving better results with automatic speech recognition technologies (necessary to test on customer data first). Input: audio file (format details – see…

For evaluating the real life scenario of Phonexia Speaker Identification technology, the system needs to be calibrated by SID dataset. SID dataset (minimum requirements): To measure SID performance precisely, it’s important to prepare evaluation recordings set very carefully. The requirements are: 50+ known speakers, 200+ recordings in total (i.e. 3 to 5 recordings per speaker*) 1+ minute of net speech…
To create the SPE report: Go to the SPE installation directory Open command line/terminal (in Ubuntu Linux Right click + press E, in Windows type cmd in the address bar) Run ./phxadmin –report (Linux) or phxadmin.exe /report (Windows) Zip up the created directory with report and attach the ZIP file to your issue description The Report functionality is not present…

…happen if the initialization of SPE engine takes too long. Phonexia Browser software treats it as initialization failure and kills the server. You can fix this by doing the following: Increase timeout in Settings > Speech Engine tab > First connection timeout Use fewer instances of technologies, thus letting the Speech Engine to start faster Use smaller models of technologies…
