…5th generation (RU_RU_5) of STT/KWS. STT word accuracy (WAcc) is increased up to 90,8 % (up to 7.1 p.p. improvement). Polish (Poland) new-generation PL_PL_6 model: It is an upgrade of previous 5th generation (PL_PL_5) of STT/KWS. STT word accuracy (WAcc) is increased up to 85.3 % (up to 18.7 p.p. improvement). Italian (Italy) new-generation IT_IT_6 model: It is an upgrade…
…STT model, put its name in the model parameter, like this: GET /technologies/stt?path=foobar.wav&model=<customized_model_name> Using customized STT model in command line STT To use customized STT model in command line STT, simply specify the new configuration file belonging to the customized STT model in the -config parameter. For example, assuming that original pl_pl_5 model was customized, specifying updated as the model…

…to use preferred phrases containing such ‘unknown words’, it’s necessary to add these words to the language model first, using LMC – see STT Language Model Customization tutorial then perform the transcription using the customized STT model, specifying the preferred phrases in the POST /technologies/stt or POST /technologies/stt/input_stream REST call. Note: The REST call body does not allow specifying custom…
Adding words to STT language model on-the-fly is possible in SPE 3.45 or newer as part of preferred phrases feature. The POST /technologies/stt or POST /technologies/stt/input_stream API calls actually serve two purposes: specify the actual preferred phrases (in the phrases part) specify words to be added to STT language model (in the dictionary part) Each part can be used independently,…
…numbers conversion is based on set of grammar rules, describing how the conversion should work. Conversion rules are stored in numeric.pegjs file, located in grm subdirectory inside the STT model directory. For example: in Czech 6th generation STT it’s located in {SPE_directory}/bsapi/stt/data/models_cs_cz_6/grm in Spanish 6th generation STT it’s located in {SPE_directory}/bsapi/stt/data/models_es_6/grm Can it be extended or tuned? You can edit…
…SID4C (SID4 extractor and SID4 comparator) with both L4 and XL4 models, depending on actual availability of the technologies/models in that SPE installation.

…CPU cores in the server. Example: Czech STT on stream is approx. 4 times faster than realtime, i.e. 1 CPU core can process 4 realtime streams simultaneously. So a server with 8 CPU cores running only STT stream can be configured as follows: keep 1 core dedicated for operating system and SPE remaining 7 cores can handle 28 realtime workers…
…TEXT (used for STT language model training) MSA is used in all formal writing such as official correspondence, literature, newspapers, webpages so there is no problem to accumulate loads of texts, but it will be more formal and far from spontaneous speech Support for MSA in Phonexia products Name LID L4 STT Description Arabic (MSA) arb — Modern Standard Arabic,…

One of the improvements implemented since Speech Engine 3.24 is neural-network based VAD, used for word- and segment detection. This article describes the segmenter configuration parameters and how they are affecting the realtime stream STT results. The default segmenter parametrs are as shown below: [vad.online_segmenter:SOnlineVoiceActivitySegmenterI] backward_extensions_length_ms=150 forward_extensions_length_ms=750 speech_threshold=0.5 Backward- and forward extension are intervals in miliseconds, which extend the part…
