Spanish -> English Transcription translations not working

[sam9 (Sam)]

Description
When using the live transcription feature in the video sdk if I set the speaking language to spanish and the translation language to english I’m not receiving the english tranlsation for the caption. It looks like spanish → english is supported when I check supportedTranslations.translatedToLanguage. Also interestingly Spanish → French is working so I know my code is setup correct enough.

Which Web Video SDK version?
1.12.10

Video SDK Code Snippets

const transcriptionClient: typeof LiveTranscriptionClient =
                videoRoom.getLiveTranscriptionClient();
            const status = transcriptionClient.getLiveTranscriptionStatus();
transcriptionClient.setSpeakingLanguage(LiveTranscriptionLanguage.Spanish);
transcriptionClient.setTranslationLanguage(LiveTranscriptionLanguage.English);

To Reproduce(If applicable)
Steps to reproduce the behavior:

1. Initialize transcriptionClient
2. Set speakingLanguage to spanish
3. Set tranlsation language to english
4. No english translation caption message fired.

Troubleshooting Routes
Have found that spanish to french works with same code.

Hey @sam9

Thanks for your feedback.

I followed your steps and retried; it successfully translated Spanish to English. Could you check if there are any issues with the calls?

Also, setTranslationLanguage does not apply to all in-session users; it only applies to the current user.

Thanks
Vic

Thanks @vic.yang !

So on further testing it does work… however it takes a sold 15-30 seconds of talking to kick in?

Other languages such as French seem to kick in a little earlier but for some reason English takes a bit to get started…

Not sure if this is a known limitation or behaviour.
