    I am currently looking into a proof of concept transcription system for
    doctors in an A&E department. There are a dozen doctors with various accents
    of English both British and Non-British such as Indian English.

    Firstly, how would the setup be for catering for diverse accents? For example
    would I need multiple acoustic and language models?

    Secondly, should I create a new acoustic model bearing in mind that the
    acoustic models that are available for CMU Sphinx are for US English or should
    I adapt one of the available models for British English?

    Hello

    For example would I need multiple acoustic and language models?

    For the proof of concept no, for the futher operation maybe yes

    Secondly, should I create a new acoustic model bearing in mind that the
    acoustic models that are available for CMU Sphinx are for US English or should
    I adapt one of the available models for British English?

    The design of the system must be considered in the context project you want to
    try to accomplish. You can both train user-specific models, use adaptation
    profiles or just use generic model. User-specific model requires you to have
    more than 20 hours of the accurate transcription for that specific user. It's
    up to you to decide if you want to record each of your doctor. Adaptation
    improves with 20 minutes of dictated text. Generic model will not require any
    enrollment. Accuracies will be different too. The implementation complexity is
    also different.

    For the proof of concept you can go with a generic British model. You will
    have way more issues with the language model for medical dictation.

    You will have way more issues with the language model for medical dictation.

    Thank you for your response. With regard to the issues with medical dictation
    do you mind elaborating on the issues I may encounter?
