Arabic dialects in Phonexia LID and STT

…code ar-XL, where the XL means “cross-Levantine” 😉 NOTE: To get the best STT results, use the model that corresponds to given dialect. The AR_XL_* model is best suitable for Levantine dialect recordings. When using AR_XL_* model for neighbor dialect, e.g. Iraqi, the results will be much worse… and for e.g. Maghrebi, the results will be most probably completely unusable….

May be done in Phonexia using anonymized data (= language-prints extracted from a .wav audio) in FAQ…

Understand SPE multithreaded technologies initialization

…rather for stable environments, e.g. production deployments. Note that separate threads are used only for distinct technology–model combinations. Multiple instances of the same technology–model combination are NOT initialized in parallel. The number of threads used for the multi-threaded initialization can be configured using server.technology_multithread_initialization.n_threads setting. Default value is 0, which determines the number of threads automatically according to number of…

Understand SPE home directory

…uploading file using POST /audiofile physically creates the file on filesystem in the storage location… and the file stays there until it’s explicitly deleted using DELETE /audiofile. There might be various reasons to NOT use the REST API for uploading files to the Speech Engine, e.g. to save the server from unwanted burden caused by many uploads and/or big files……

Understand SPE configuration

…# The value specifies the maximum number of archived log files. If the number is exceeded, # archived log files are deleted, starting with the oldest. # server.logging.file.purge_count = 5 The following directive is important mainly for tuning and initiation of the SPE. Turn it on when the system is prepared to go live. # Use separate thread for logging….

…technological model and can range from 5 to 50 times faster than real time on 1 server CPU core. Voiceprint extraction is the most time-consuming part of the process. Voiceprint comparison, on the other hand, is extremely fast – a millions of voiceprint comparisons can be done in 1 second. Voiceprint extraction (Speaker enrollment) Speaker enrollment starts with the extraction…
