I use an iPhone4 app called iTalk to record conversations with my supervisor and other audio material. I also use Dragon Naturally Speaking 12 (DNS) to dictate my work into Word. I wondered if it may be possible to get iTalk to link to DNS. I found a tutorial video which explains how to do it wich you can view from here.
The procedure is quite straight forward, it just needs the .aiff file from iTalk to be converted into a .wav file which is easy enough with the free software Audacity which you can download from here. If you have not come across Audacity before it is a good general purpose audio editor.
The process makes use of the transcription option in DNS. Although this technique will work with mixed voices the translation can be a bit bizarre. I am going to try it with just my voice only as a test and see if that is any better.
