I've managed to confirm that the Tecra M4 indeed has a Mic Array. That's good. I've also confirmed that the speakers are blocked in tablet mode. That's bad. I just found out that my tablet has shipped and is on its way to me. That's good.
From my correspondence with my helpful Toshiba Rep:
I asked about the Mic Array and the Speakers on the Tecra M4:
I have question about Mic Array and Speakers on the M4
I've been reading the materials from the web site. I have two questions about the M4 that I have purchased.
Table PCs usually have a Microphone Array consisting of 2-4 microphones that are built-in to the side of the case, for voice Dictation with the Tablet PC Operating system. Can you tell me about the Mic Array on the Toshiba Tecra M4? I do not see any information about this on the web site.
I am looking at the PDF picture of the new M4. From the picture, it appears that the stereo speakers on the M4 will be obscured and the sound blocked when I demonstrate the tablet to my clients in tablet-mode. Is this correct?
My Toshiba representative promptly responded:
This is what I found out regarding your questions. Also the speakers will be blocked when you are in tablet mode. Here is the information I received from Toshiba regarding the microphone array on the M4: The Mic Array determines the direction of sound source input to the microphone and suppress sound from outside specified range and surrounding noise.
I followed up to ask about the Mic Array:
I understand, from your email, that the speakers will be blocked when in tablet mode. That's discouraging. I hope I will still be able to use multimedia functions while in tablet mode.
What about the microphone array?
1. Please let me know if the mic array will be blocked from use when in tablet mode as well.
2. Please let me know how many mics make up the array. (Typically 3-4 individual mics. The screen shot appears to imply 3 mics).
To which, my representative responded:
No the mic array will not be blocked since it is located on the display
panel. There are 3 individual mics.
