I’ve been using the CapTel for a few years, but the ClearCaptions Ensemble has a 90-day trial period. So I figured I had nothing to lose by trying it out.
Before I get to the captioning quality, which is admittedly the most important aspect, here are a few notes on other aspects of the phones:
The CapTel phone is decidedly unsexy. It is pretty old, large and clumsy. I’ve been using the 840i, which does not have a touch screen, for a few years. However, when I went to the CapTel site, I see they now have a touchscreen version, the 2400i. I may have to try that in the future.
The ClearCaptions Ensemble looks much nicer. It is also all touchscreen, except for the power button. However, the touchscreen interface is horrendous. As I said to a friend, “It has a touch interface, but you wish that it didn’t.” When dialing a number, there is no delete if you make a mistake. In addition, the dialpad changes to an awkward double row of numbers when you’ve already entered a few of the numbers you’re trying to call. In short, there is zero usability advantage in the fact that the Ensemble has a touchscreen, and usually it is less usable than the clunky CapTel 840i.
Obviously this is the most critical aspect of a captioned phone. Below I’ve posted a video with a side-by-side comparison. I used a YouTube video of a person speaking, to ensure that the audio was identical for each trial. Go ahead and check out the video first. I apologize in advance for some of the shaky camera work. My hands were starting to get very tired (see below for an explanation).
As you can see, the speed and accuracy of the CapTel phone is superior to ClearCaptions. Not seen here is the dozen or so trials I did with the ClearCaptions phone, using a different, lower quality video that better portrayed a one-sided phone call. Most of the time, the ClearCaptions phone did not caption anything, and I had to start the call again. The CapTel phone never had any issues with the other video. (This is why my hands (and I) were getting so tired/shaky.)
Additionally, one of the aspects of the ClearCaptions phone that I was excited about is that it supposedly integrates human captioning with automatic/computer-generated captioning. This supposedly makes it faster.As a computational linguist/NLPer, this sounded great! However, as can be seen above, there is no speed or accuracy advantage. When making real calls with the ClearCaptions phone, there are many times when the automatic captions are completely incomprehensible.
While I love sleekness and gadgetry in my smartphone, the most important aspect of a captioned landline phone is reliability: It just has to work. The CapTel phone works faster and more consistently. That’s really all I need to know.
