Worker is a working thread performing the actual files– or realtime streams processing in Speech Engine. This article helps to understand the Speech Engine workers and provides information how to configure workers for optimal performance and server utilization. Starting from SPE 3.51, new defaults in settings/phxspe.properties make SPE to configure workers automatically according to local conditions (physical CPU cores, configured…

…normalization. The Audio Source Profile includes: a set of calibration voiceprints extracted from the source files NOTE: these voiceprints are not compatible with standard voiceprints created using the /technologies/speakerid4/extractvp REST API endpoint or the vpextract4 command-line tool! information about profile version, creation date and version of voiceprints hash of all data in the profile and hash of its parent profile…
…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……

…– results are then returned immediately from the cache instead of complete re-processing of the audio file. Own persistent data storage SPE keeps uploaded audio files in its own persistent storage space, so the original source files can be archived or deleted after upload. Data privacy SPE keeps information about audio file or stream only as long as the file…
…(taking longer time to synthesize). Connector naming, location, configuration TTS connectors should be placed in {SPE_installation_directory}/external/technologies/tts directory, each connector in a separate subdirectory. To enable a connector, include its subdirectory name to the external.technologies.tts_connectors setting in SPE configuration file. Connector executable file must be named connector (i.e. without file extension). Connector configuration – like TTS service address, access credentials, API…
…and fixes Speech Engine: General Reduced RAM consumption (since 3.58.0) RAM consumption can be up to several gigabytes lower, depending on technologies configuration and processed audio. This is mainly visible in Speech To Text when processing many audios or longer audios (or both). The effect may be less visible in other technologies. Fixed issues with non-ASCII / Unicode file names…
…of crucial files like SPE configuration file, etc. it’s strongly recommended to use visual comparison tool (Beyond Compare, KDiff3, …) based on the differences, make a decision about needed changes – which directories/files can be overwritten and which files contain changes made by you, i.e. in which you need to merge your own changes with their new content (this typically…

…sheet demonstrating the sigmoid function: Score-to-Confidence. Score-to-confidence conversion tuning Starting with SPE/BSAPI 3.24 (October 2019) it’s possible to modify the confidence calculation using confidence_shift and confidence_sharpness values in user configuration file in [score_calib:SKeywordScoreCalibrationI] section. User configuration file must have the same name as original configuration file, with added .usr extension, e.g. kws_en_us_5.bs.usr – see the What is a user configuration…
