Is the Nexus One the only Android phone having 2 microphones?
I know that the 2nd microphone is intended for helping noise cancellation and I need this feature for my software development project.
I am wondering whether the Nexus One is the only such Android phone. That is, if I need to program for this feature, must I purchase a Nexus One only?
The Motorola Droid, Droid 2, and Droid X all have dual microphone noise reduction as well. However, I am not sure if this always enabled when the microphone is active, or if it only works during calls. Also, I'm not sure how that would help with text to speech (TTS). Do you mean speech to text/speech recognition?
If you need GSM phones, look (depending on your location, inside or outside of the US) at the Motorla Charm, Backflip, Milestone 2, and Droid 2 global (CDMA & GSM). I just noticed that it may seem like I'm pushing Motorola. I'm not. These were the only phones which clearly stated they had two microphones for noise cancellation that I could find after quite a bit of Googling.
