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…
…kept in the database at all. Supported databases SPE supports SQLite and MariaDB 10.x (SPE 3.46+) MySQL 5.x (SPE up to 3.45) database engine. The database engine is configured in phxspe.properties SPE configuration file – see the Database section of SPE configuration file article for more details.

…technologies setup. If we assume that the whole machine is dedicated as a “speech computing unit” then, in general, we can calculate it as follows: file: phxspe.properties server.n_workers = <#_of_core> file: technologies.xml (no. of threads per technology, can be also set up by the phxadmin tool) SQE: <#_of_cores>/4 VAD: <#_of_cores>/2 other technologies: <#_of_cores> RAM: 8 cores = 32 GB 16…
…Added utterance_length to SID/SID4 voiceprint results New: Added /output_stream and audio file player (/utils/player/output_stream) endpoints New: Added 5th generation of AR_XL (Arabic Levantine) (Beta version) of STT, KWS and PHNREC (combines both North- and South Levantine, hence the custom code AR_XL) Changed: Changed endpoints, results and properties using the term ‘stream‘ to use ‘input_stream‘ check the SPE REST API documentation…
SPE home directory is an analogy of user home directory in operating systems (e.g. /home/ in *nix, /Users/ in macOS or Windows, etc.) – it is the place where SPE stores data for users configured in SPE. Default SPE home directory location is {SPE_installation_directory}/home/. This location can be changed using server.user.home setting in phxspe.properties SPE configuration file. Changing the home…
…audio conversion tools. Tested with sox or ffmpeg. For the configuration of this functionality, see [SPE]/settings/phxspe.properties Note: You should be aware that audio format conversion (e.g., if the original audio format is highly compressed) can decrease the accuracy of speech technologies. Integration Possibilities Phonexia Speech Platform can be integrated into a partner’s application using the Speech Engine component (REST API)….
…phxspe.exe. FFmpeg: https://ffmpeg.org/download.html SoX: https://sourceforge.net/projects/sox/files/sox/ (The FFmpeg is a bit ‘cleaner’ choice on Windows, since it’s available also as single-executable static build, unlike SoX whose 10+ DLLs clutter up the SPE directory) SPE configuration As a next step it’s necessary to enable and set up the converter in SPE configuration file (in settings/phxspe.properties). Set the audio_converter.enabled to true to enable…
…for storing SID speaker model metadata – textual properties like name, date of birth, etc. are stored as JSON file (note: the structure and meaning is defined and understood by Browser itself, not by SPE), speaker photo and any other files attached to the speaker model are stored as separate files. Another example would be the information about content of…
…Download the latest version from https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-essentials.zip After unzipping the package, move the ffmpeg.exe executable to the /SPE/ directory.
