Version: 3.5.0

Release notes

Speech Platform Virtual Appliance 3.4.0, 2024-11-21

Added Audio Quality Estimation technology (high-level description) in REST API.
Voice Activity Detection technology (high-level description) is available in both REST API and GUI.
Speech Translation technology is now fully working in GUI.
Speaker Diarization technology (high-level description) is now fully working in GUI.
Updated the Speaker Identification model to xl-5.1.0, which is capable of carrying out automatic adaptation to various input audio sources (YouTube, Skype, WhatsApp, VoLTE, AMBE).

Added Speech Translation technology preview in GUI.
Added Speaker Diarization technology in (high-level description) REST API (still only preview in GUI).
Added option to speed up Enhanced Speech to Text Built on Whisper via beamSize parameter in Virtual Appliance configuration file - smaller beamSize means faster processing (up to ~30% with large_v2 model and beamSize=1) at the expense of slightly lower accuracy.
Speech to Text Phonexia and Time Analysis of Speech technologies updated to version 3.62.0.
Configuration and administration changes:
- Added support for importing Virtual Appliance to Microsoft Hyper-V.
- Both system and data disk now automatically resize according to size set in virtualization software.
- Customers can now use cloud-init with Virtual Appliance.
- Added diagnostic script for collecting logs for troubleshooting.

Included Components

Language Identification technology (high-level description) now fully working in GUI.
Added Gender Identification technology (high-level description) preview in GUI.
Added possibility to share a GPU among multiple technologies, to better utilize the hardware resources.

Included Components

New and significantly easier way to install or update technology licenses - they are now loaded from a separate YAML file. Just unzip the licensed models package to the data disk and the system loads the licenses automatically.

⚠️ NOTE: The new license format is not compatible with previous versions, i.e. licenses used in earlier Virtual Appliance versions cannot be used in this version and a new license needs to be obtained from Phonexia.
Added Language Identification technology (high-level description) preview in GUI.
Added Speaker Diarization technology (high-level description) preview in GUI.
Added possibility to run Voiceprint Extraction on GPU to significantly boost the extraction performance.
Virtual Appliance configuration changes are now automatically applied to corresponding components (no restarts needed anymore).
Lower memory consumption during processing due to internal components optimizations.

Included Components

The Speech to Text Whisper Enhanced technology has been renamed to Enhanced Speech to Text Built on Whisper and a new Language switching feature was added. This feature identifies the predominant language spoken within each thirty-second interval of audio and the identified language is then utilized for transcribing that particular section.
For Speech to Text Phonexia and Time Analysis of Speech technologies it's now possible to configure the number of tasks to be processed in parallel. It is done using the paralelism parameter in the corresponding sections of Virtual Appliance configuration file.
