…less likely, but still possible to appear. This can reduce the number of scored languages from ~80 languages (included in the default out-of-the-box language pack) to like 20 or even less languages. In both cases, limiting the number of languages in a language pack results in the scores being distributed among less languages, i.e. the score values getting higher with…
Some packages are distributed with only a limited set of speech technologies and languages or without speech technologies. First installation Our software is distributed as a ZIP file. Installation procedure is as simple as: unzip the archive paste additional KWS, STT… models paste the license.dat file to the root directory where you have BROWSER folder and run_browser(.exe) script run the…

…on which technologies are included in the particular SPE installation. For testing and first-time evaluation we usually include the full set of technologies, other installations may contain only limited subset. Location of bsapi directory can be modified using bsapi.path option in SPE configuration file. This might be useful in complex network infrastructure, for sharing technologies between multiple SPEs, and similar…
…capabilities of the TTS service is not a good idea as it might potentially get incorrect over the time, leading to obscure issues in the application relying on the info.

The server.technology_multithread_initialization setting in SPE configuration allows SPE to initialize instances of technologies during startup using multiple parallel threads. Default setting is OFF, i.e. instances of technologies are initialized using single thread, one-by-one. This allows easier tracking of eventual issues during SPE startup and better readability of technologies initialization log messages (only single initialization happens at a time). The downside…
…happen if the initialization of SPE engine takes too long. Phonexia Browser software treats it as initialization failure and kills the server. You can fix this by doing the following: Increase timeout in Settings > Speech Engine tab > First connection timeout Use fewer instances of technologies, thus letting the Speech Engine to start faster Use smaller models of technologies…
Before designing and developing the application, we encourage Partner to find clear answer for the following questions: Customer requirements: Do my customers need file processing (audio) or stream processing in real time? What is the human power of the customer that can analyze the results? How many minutes per day or streams in parallel do my customer need to process?…
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…
…example: When using Czech STT on realtime streams, the results show that system outputs end of segment too often, i.e. longer pauses between words made by the speakers are misidentified as end of sentence, while in fact the speakers actually continue to speak. So it is desired to finetune the system to accept longer delay between words without ending a…

A: The following is recommended: For adding new language to language pack 20+ hours of audio for each new language model (or 25+ hours of audio containing 80% of speech) Only 1 language per record For adapting the existing language model (discriminative training) 10+ hours of audio for each language May be done on customer site.

Language Model Customization tool (LMC) provides a way to improve the Speech To Text performance by creating customized language model. Language model is an important part of Phonexia Speech To Text. In a simplified way it can be imagined as a large dictionary with multiple statistics. The Speech To Text technology uses this dictionary and statistical model to convert audio…
