Releases and Changelogs (SPE)

…user accounts Speech Engine 3.50.1, DB v1901, BSAPI 3.50.1 (2022-04-05) Fixed: Wrong pronunciations of some foreign words in STT model CS_CZ_6 Fixed: SPE may respond with STT result version 5 instead of version 6 if result was found in cache Fixed: Hardware profile file contains extra NULL character Due to change in STT results content, all STT results are removed…

Measuring of a software processing speed – what is the FtRT (Faster than Real Time)

…removed. This metric is useful for comparing technology performance on different hardware configuration, or comparing performance of the same type of technology produced by different vendors. Same recording with silence segments stripped and only speech segments kept in waveform Calculation formula is very simple and is the same for both use-cases: FtRT = audio_length[s] / processing_time[s] Example Original audio length…

Understand SPE benchmark

The SPE benchmark feature is great tool for quick and simple evaluation of processing speed directly on your hardware and using your audio files – simply call the …/benchmark endpoint corresponding to the technology you want to benchmark and wait for the result. The benchmark result summarizes the length of the processed speech, the processing time and the resulting Faster-than-Realtime…

Download Speech Platform

Step #1 – Download Try and evaluate all Phonexia speech technologies either via REST API using Speech Engine, or using the demo/testing GUI application named Phonexia Browser. Hardware requirements recommended: Intel Core i7 or better, 32 GB free RAM, 10+ GB storage (SSD preferred) minimum: Intel Core i5, 16 GB free RAM, 10 GB storage (SSD preferred) To prevent various…

Designing and Developing Application

…specific hardware (mainly CPU, virtualized infrastructure vs. HW) or are you going to buy specific HW for customer? What is short/long time storage requirements (ie. audio and results availability, desktop vs. distributed system)? Is there any synchronization required (ie. voiceprint database to clients)? What is the topology of the solution/app (ie. where to store audio, voiceprints, results, …)? How to…

…particular order or agreement under the following terms: 1.1 The Client may use the Software only for the duration of a valid license file generated by Phonexia; 1.2 The Client shall run the Software on its own or outsourced hardware and agree to do so at its own risk; 1.3 The Client may use the Software for which Phonexia requires…

SID4 performance on Intel® Xeon® Platinum 8124M

…reserved physical core count is enabled in virtual machine. With Phonexia SID4, Hyper-Threading does not bring any advantage on the hardware configuration shown above, because Phonexia technology can utilize the whole physical capacity of the given CPU in its physical cores. Thus, Hyper-Threading, as a part of CPU virtualization, can’t deliver better performance based on this parallel computation paradigm.  …

Understand SPE technologies, instances and workers

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…

Understand SPE configuration file

…article Tasks server.n_workers, server.n_realtime_workers # Multithread settings # Default value -1 means check for technologies configuration and hardware resources and set workers accordingly: # server.n_workers: either number of configured offline technologies, or number of physical CPU cores, whichever is lower # server.n_realtime_workers: number of configured stream technologies server.n_workers = -1 server.n_realtime_workers = -1 Sets the number of task workers for…

Download Voice Inspector 5.2

…models VIN application (graphical user interface, GUI) with the following technologies in-build Speaker Identification (SID4_XL5) Speaker Diarization (DIAR) Voice Activity Detection (VAD) Speech Quality Estimator (SQE) Phoneme Recogniser (PHNREC) example population sets and audio (in ./examples/) and example report templates (in ./templates/) Hardware requirements minimum – CPU: Intel® Core™ i5, RAM: 4 GB, Required HDD space: 0.5 GB for software…

Understand SPE processing queue

…can be handled simultaneously is defined by server.n_workers for audio files processing and server.n_realtime_workers for realtime streams processing settings in SPE configuration file. This is by default set automatically, based on your hardware and software configuration – see How to configure Speech Engine workers article. The picture below demonstrates the queue processing (for the sake of simplicity, technologies assignments to…

Release Notes

…more user-friendly as it can configure its workers settings automatically based on detected hardware and technologies configuration. Speech Engine (SPE) now distributed also via DockerHub – simply search for phonexia/spe. The CMD/CLI interface now part of Speech Engine (SPE) package – phxcmd[.exe] binary is now included in SPE’s folder, so technologies can be easily tested using command line interface. Phonexia…
