Speaker Syntactic Errors - what should I do?

For instance, if it were for dubbing a video, for some reason evidencing that the lady (?) is uneducated, you would preserve such errors or, at best, create equivalent ones in the target language. However if the main reason to have you translate is to publish her views/ideas in another language, you should correct all errors.

Once a very experienced video dubber taught me: If the person onscreen stutters, makes mistakes, stumbles on words, changes the subject halfway on a phrase, it's natural. If the dubber follows suit, it's amateur translation and incompetent dubbing. That's why it's OK to dub trained actors and speakers, however improptu statements made by a John Doe on the street look better when subtitled.

I would have to agree with José and Flavia. It depends very much of the purpose of the transcribed text. I would check with the client before delivery.
To give you an example, in transcriptions of interviews with psychiatric patients it is extremely important to transcribe even the sounds they make, when they pause, how many times they go "errr", the exact words they use and the way they speak. If your client has not provided clear instructions and you have doubts, you need to ask your client. I would not assume it is not important unless the client confirms it.
