…tool which SPE configuration file to use Default Speech Engine configuration file is settings/phxspe.properties. However, when using Phonexia Browser in “SPE on localhost” mode (also known as “Embedded SPE”), the configuration file is settings/phxspe.browser.properties. (Make sure to use the right configuration file, otherwise you might register the language pack to different configuration and therefore it won’t be visible where you…

…– recordings from different speakers representing the source data, minimum 60 seconds net speech in each. The set must not contain duplicates or target speaker recordings. With FAR Calibration, the system is calibrated to a specific False Acceptance Rate (e.g., FAR = 1%) for each reference voiceprint (speaker model). Only one side (the enroll) is calibrated, using data representing the…
…The Speech Platform includes the following technologies. Technologies are available in the Speech Engine component based on its particular configuration (Voice Biometrics, Transcription System, etc.) Speaker Identification (SID) – recognizes a speaker automatically based on their voice, Speaker Diarization (DIAR) – separates multiple speakers in mono audio automatically, Language Identification (LID) – detects the language or dialect spoken in a…
…SPE in the {SPE}/data/benchmark directory. The second option uses single audio file of your choice uploaded to SPE storage, specified by the path parameter. The set of audio files supplied with SPE contains recordings of various length (from 30 seconds to 5 minutes) and with various speech/non-speech ratio. This is to account for the fact that both the length of…
…n-grams. Using this the user can adjust a language model focusing on a specific domain to get better results. Result types During the process of transcribing the speech there are always several alternatives for a given speech segment. The technology can provide one or more results. 1-best result type provides only the result with highest score. Speech is returned in…

Set the audio_converter.enabled to true to enable…

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…
…expected to provide information about actual TTS service capabilities: list of voice names, supported languages and audio quality (sampling frequencies). This info is used during SPE startup sequence – TTS connectors enabled in SPE configuration file are started with –info parameter and SPE reads the connector output. Connectors failing to provide the info won’t be available for use with SPE….

…in our example is 36 seconds. After stripping silence, it gets 14 seconds – this means that original audio contains 38% of net speech and 62% of silence. Phonexia speech technologies analyze the entire recording, but pick only the speech segments for AI processing, i.e. the absolute processing time will be practically the same… Creating voiceprint by Speaker Identification took:…
