Further, one important property of the update controller ϕ(n) is that it should never fail to activate when speech is present.
The similarity between the brain regions activated by speech in this study and the regions activated by tones (Opitz et al. 2005) could not be explained by the analysis of the physical sound features.
Overlap is also observed between brain regions activated during speech production and the precentral gyrus region activated during perception of degraded compared with clear syllables (as depicted in Fig. 4 Ai, this consists of 90 2-mm isotropic voxels with a center of mass at [-46 0 32]).
Brain regions maximally activated by speech in noise are different from those maximally activated by speech in quiet, suggesting that difficult-to-understand speech requires the mobilization of different brain areas.
However, the nature of the representations that are activated in motor regions remains unclear, and overlap with regions activated during speech production has not been unambiguously shown.
Once the fish is activated, digitized speech and music play and the corresponding motors turn the head, flap the tail and open the mouth in synchronization with the words.
An even simpler version is the kind of web kiosk with a touch-screen that is springing up in cities such as Singapore and Toronto.Many people will be able to do as much business as they need over the Internet with inexpensive smart mobile phones, some of which will soon take the form of a wrist-watch that can be activated by speech rather than via a fiddly keypad.
These findings raise the possibility that orthographic codes are mandatorily activated in speech production by literate speakers.
In teens whose verbal IQ scores had increased, for example, the scans showed increased gray matter density in a region of the brain activated by speech.
Moreover, regions associated with performing arts training were not necessarily activated by speech in violinists.
