Jott as a diction-checking device

I’ve blogged before about Jott, the web service which lets you call in and leave a voice message, and then it transcribes it to text and emails it to you or others you want to contact. I use Jott quite often in lieu of a voice recorder for quick thoughts that might be actionable. When I want to catch an idea, I get my cell phone, hit “5” on the speed dial to call Jott, then talk through my message. A few moments later, I get a transcribed version in my GMail inbox which then gets reviewed at my next GTD weekly review.

Jott’s capabilities as a speech-to-text converter are impressive, but it’s not perfect. When I get a mis-transcription, sometimes I wonder whether it’s Jott’s fault or whether it’s something having to do with how clearly I am speaking. Take this recent message for instance. I had just finished teaching a section on exponential growth and decay in my calculus class that meets this summer. I wanted to leave myself a quick note for my GTD review about things I needed to work on with the presentation for this section. Here’s what I said:

I need to edit the 3.8 presentation. The example on Newton’s Law of Cooling didn’t quite work. Need to add a question as to what the C represents in Newton’s Law of Cooling. It just went too long. I think one decay example, one growth example, one Law of Cooling and that’ll be enough. Maybe flesh out a little bit more what a differential equation is, they were a little lost.

Now, on the other hand, here’s what Jott thinks I said (differences are in boldface):

I need to edit the 3.8 presentation. The example on Newton block cooling didn’t quite work. Need to add a question as to what the C represents in Newton block cooling. I just went too long I think one decay example, one growth example,in block cooling that’ll be enough. Maybe flush out a little bit more for the differential equation is, they were a little lost.

Newton block cooling“? I went back and listened to the voice message and, to me, I am clearly saying “Newton’s Law of Cooling”, but Jott went 3-for-3 in transcribing this as it did. That makes me wonder if my students would hear me say “Newton block cooling”. Students are more intelligent than a computerized speech-to-text processor, but still, if this advanced technology is convinced that I am not saying “law of cooling” but “block cooling”, there’s a pretty good chance I am not being clear enough.

So perhaps Jott would be useful as a diagnostic tool for a speaker’s enunciation and clarity — if there’s 100% agreement between what the speaker actually said and the Jott transcription, then there are no problems with clarity; otherwise, there might be.

  1. Do you train it for your voice and dialect first, or just go straight to work?


  2. It seems like when I first used Jott, there was a link in the email transcription that let you rate the accuracy of the transcription. Now I don’t get that. Maybe new users get that option for a while until Jott is “trained”.

  3. Dude. This is cool. Is this service for free..??

  4. Yes, it’s free.

    For implementing GTD you might try out this web-based application:

    You can use it to manage your goals, projects and tasks, set next actions and contexts, use checklists, schedules and a calendar.
    A mobile version is available too.

    As with the last update, now you can add or invite Contacts, and share your Projects and Contexts with them.

    Hope you like it.
