The legacy V1 API that the Batch Virtual Appliance currently supports will be removed by February 2022. The V2 API as used in the Speechmatics SaaS (https://asr.api.speechmatics.com/v2/docs) is now supported in the Batch Virtual Appliance. We recommend all customers move to using the V2 API. Please see the section How to use the V2 API.
The new enhanced model requires increased compute requirements and new recommended AVX flags. Please check the updated system requirements in the installation guide and ensure your hardware meets Speechmatics' recommendations. Otherwise you may see a slow down in processing speed when using the enhanced model. It is also now necessary to run the appliance on processors that support AVX2 in order to take advantage of latest performance optimisations for both the standard and enhanced model for all language packs.
If you are importing an appliance through VirtualBox, and AVX flags are not automatically enabled, you can also take advantage of the the performance benefits from AVX2 following these guidelines.
