Learning experience with technologies

Few days ago I was reading Dr. Helen Barrett’s blog.  I used RSS feed app on my iPod touch to get the message. The topic is about her learning experience in Spain by using an iPhone app, namely Dragon Dictation.  The distinctive feature is that user can record voice and the voice will be converted into texts.  The texts then can be sent through either email or SMS in a minute.  The first applause is that the quality of recorded voices is good. However, the processing time is a bit long – converting 30 second sound takes about 1-2 minutes for about twenty words.

Although the developer (Dragon Speak Naturally) is focusing on voice recognition. I remembered that in 1998 I used ViaVoice for a voice recognition project and felt magnificent of the features. ViaVoice was more accurate on voice recognition probably due to its pre-training feature.  That is, different accents and pronunciations were recorded by the build-in engine as one’s voice profile.  However, this function is not available in this iPhone App, so the engine might not recognise the voice accurately.

Nevertheless, it is a positive sign of technological advancement or a trend to record one’s instant idea before sharing as a post on one’s own blogfolio. The ideas could be further refined and practical in education. It could be beneficial if the App can be installed in iPod Touch (not yet possible at the moment) since the earphone can record sound.
