My previous blog post analyzed how well recordings made on the iOS platform compared to a typical well-rated digital voice recorder for Dragon NaturallySpeaking (DNS) transcription. I tested the Voice Memos app that comes preinstalled on most iOS devices (the exception being the iPad) and the Andrea PureAudio Live Recorder app which was recommended by Nuance at the time.
But in October 2011 Nuance released its own recorder app for the iOS platform: Dragon Recorder. While I haven’t applied the analysis procedure to this app as outlined in my Recording on the iPhone for Dragon NaturallySpeaking Transcription blog post, the following feature comparison shows that Dragon Recorder nicely fits the requirements for DNS users looking to create recordings for transcription on the iOS platform.
Note however that Nuance says: "While the Dragon Recorder app introduces more customers to the freedom and flexibility of remote dictation, customers requiring advanced recording functionality can continue to rely on Dragon’s ability to transcribe the audio files of the industry’s leading digital voice recorders."
