…it can help in other applications, too – e.g. when transcribing domain-specific audios, the frequently used domain-specific phrases can be boosted. How preferred phrases work The picture below shows a simplified standard speech transcription process – the digitized speech signal spectrum is analyzed in the neural network acoustic model (which describes the pronunciations of a given language) and goes into…
Certain SPE entities – SID Speaker models, SID Audio source profiles, LID Language packs – can have additional information associated with them in the form of “metafiles”. This article explains the intended usage of metafiles. In general, SPE is intended as under-the-hood engine, focusing purely on the speech-related audio processing. Any additional functionality should be done on the application layer,…
…model in Speech Engine using phxadmin 1) Placing the customized STT model in correct location In order to be recognized by Speech Engine, the customized STT model must be placed in a correct location. The best location in SPE 3.41 or newer is <SPE_directory>/shared/bsapi/stt (see Understand SPE directory structure article). In older versions it’s <SPE_directory>/bsapi/stt. The data and settings directories…

Phonexia Speaker Identification is a voice biometry tool for recognition of speakers by their voice. In this video, we will show you how to start using this technology! You will learn how to create a “Speaker Model” to identify a speaker in a set of data. Ready to test it? Start with our video: What else is needed? 1. Phonexia…
In this post, we break down the complexities of the initial installation process. By the end of the guide, you will be able to start processing your recordings with Phonexia Speech Technologies. 1. Download Evaluation package Download the Phonexia Evaluation package from https://partner.phonexia.com/kb/sp/speech-platform/evaluation-package/ Create a new directory and unzip the package into it in your desired location, for ex.

…a numerical expression of probability that word was said in a specified time frame. Keywords Keywords are not dependent on any dictionary. This allows to define specific, foreign or even nonexistent words like product names. However, only allowed graphemes (symbols) from a supported list can be used to define keywords. This list can be easily obtained by Speech Engine and…
Configuring Speech Engine to utilize effectively the full power of underlying hardware can get challenging – one can easily get lost in all the strange terms like technologies, instances, slots, or workers… This article should shed some light in it. Speech Engine is like post office Thinking about Speech Engine, there is actually a very nice analogy with post office…
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…
…to the other: places of speaker’s longest and shortest reaction, i.e., where this speaker stopped talking and the other speaker started talking the average reaction times number of speaker-turns in the particular direction and details about crosstalk, for example where the other speaker is talking “over” this speaker Segmentation This section is optional and need to be explicitly turned on….
This article explains details about SPE asynchronous requests processing queue, the processing task lifecycle and its handling states. When SPE receives an asynchronous API request, a task is created and put in a queue. Size of the queue is defined by server.n_task_limit setting in SPE configuration file, default value is 1000 tasks. Tasks in queue are then handled according to…
…Customers can usually only refer to captured recordings data set during a specified time period with numbers like: total number of recordings average file size of captured recording or total number of captured hours Customers usually don’t have any information about ratio between speech signal and technical/silence parts of recordings in the beginning. The speech / non-speech ratio is detected…
