Hi guys. A customer is using the Iflytek Interreco ASR. I followed Application Note here for integration:
https://www.devconnectprogram.com/fileMedia/download/fc5e531d-93df-4ef5-8956-4c8f84ea2bbe
On EP 7.2.1/ OD 7.2.1:
- when selecting 'Iflytek' as engine type, the connection was OK, the Iflytek server could return the recognition result successfully and the OD applications could get the tag value of the result;
- when selecting 'Nuance' as engine type, the connection was OK, the Iflytek server could return the recognition result successfully but the OD applications could NOT get the tag value of the result.
After upgrading EP/OD -> 7.2.3:
- when selecting 'Iflytek' as engine type (see logs below), the system seems searching for a Loquendo ASR (it does not support MRCP v2) so no connection, the Iflytek server can NOT return the recognition result and the OD applications can NOT get the tag value of the result;
- when selecting 'Nuance' as engine type, the connection is OK, the Iflytek server can return the recognition result successfully but the OD applications can NOT get the tag value of the result.

Can you provide more recent Application Notes for integration ?
Can you give us some suggestion on how to solve it ? Such as do some modification on external grammar file.
Thanks in advance.
