SPE can be easily connected with external Text-To-Speech (TTS) services using simple connector system. This article describes the principles and how-tos; following this instructions you can create your own connector, allowing to use a custom 3rd party TTS service via SPE. The TTS connector should be a command line (CLI) application or script, which communicates with the external TTS service…

This article explains the purpose and structure of SPE technologies configuration file technologies.xml, or technologies.json created by Phonexia Browser. SPE installation includes usually multiple speech technologies (e.g. Speaker Identification, Speech To Text, etc.) in various technological models (e.g. L4, XL4, etc.), or supporting various languages (e.g. 6th generation of EN_US, CS_CZ, etc.) available. You can select from these technologies/models those…
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…
SPE directly supports limited list of audio formats (codecs and containers), see Supported audio formats FAQ. Other audio formats must be converted using external tools. This conversion can be done either completely outside of SPE, before passing the files to SPE, or you can set up SPE to convert the files automatically. Then, depending on the capabilities of the conversion…
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…
