Coverting speech/audio interviews to text

[amis]

I've just started a new project where I will have many digitally recorded interviews that I need to convert into text. I understand that the results will be approximate and that I'll have to edit the text to make it accurate.

I wonder if anyone can advise the best software for this? I've seen reviews of the Naturally Speaking software from Dragon. This seems to be very good when you dictate directly into your laptop and it can get familiar with your accent, word-use etc. But I have not seen any comments as to how useful it might be where many different voices would be involved, as with interviews etc.

Has anyone had experience of this and could advise?

Thanks for any help you can give.
