Phonexia Speech Platform is provided as a set of several components: The Speech Engine (SPE) component is a REST API that includes technologies for the automated processing of audio files and audio streams. This component is usually provided in a specific configuration that meets the customer’s use case. The Phonexia Browser component is an expert-level application (on the top of…

…more keywords and optional threshold value and/or pronunciation variants of the keyword. The number of keywords and pronunciations is not limited. – to clarify this statement: The performance drop affects only processing using keyword lists without explicitly defined pronunciations. In such cases, the technology must create pronunciations internally in the background before starting the processing (see Pronunciations section below), which…
…point zero three ⇒ 1586.03 sixty four million seven hundred thousand ninety ⇒ 64700090 This should help to simplify processing of the transcribed texts by text analytic layers or NLP (Natural Language Processing) engines, e.g. in voicebot applications. Where is the converted output available? The words to numbers conversion is available only in n-best output (i.e. where the entire sentence…

A: If server responds on pending request by status 200 – OK, the body of the response will have the result inside (server already has the result in cache memory and there is no need to process the file again). If server responds on pending request by status 202 – Accepted, server will create task and server will begin to…
…technology models configuration usually introduces new features or major fixes, which may change communication between server and client, or other changes which may affect customer processes can also include new technology models; with such update you can add only the new technology, without SPE installation Upgrade changes the first version number (e.g. x.y.z to x+1) and is a major change…

Phonexia Phoneme Recogniser (PHNREC) converts speech signals into pronunciation characters (so called phonemes). After the conversion, the pronunciation (text) can be easily indexed and searched by third party text data mining tools. The technology is optimized for noisy recordings and colloquial speech, can process audio files as well as audio streams and can provide results in several output formats. Phoneme…

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,…
…dialogue. This can be used to improve calls between operators and callers or to indicate potential stress points in phone calls, for example, change of speech speed during the conversation). Input TAE can process both audio files and streams (for format details see Speech Engine documentation). By its nature, TAE is usable mainly on two channel phone calls recordings, where…
Quality of the audio is extremely important for satisfactory results of any speech processing technology, being it simple voice activity detection, speech transcription, voice biometry, or other. There are two main aspects of audio quality: technical quality of the audio data (format, codec, bitrate, SNR, …) sound quality of the actual content (background noise, reverberations, …) Technical quality Using inappropriate…
