Speech processing apparatus has a store containing a reference vocabulary of words and carries out active word selection in accordance with mode data supplied to the apparatus. After this, the apparatus performs dynamic template adaptation in dependence on the output of a sensor that monitors environmental influences on the speaker of the kind that modify speech sounds made by the speaker. The sensor may be responsive to vibration or acceleration forces on the speaker, the apparatus using information about how vowel and consonant groupings are influenced by forces on the speaker to perform the template adaptation. Pattern matching is used to compare the speech sounds of the speaker with the modified signals after template adaptation to identify the most likely word spoken.

Speech processing apparatus comprising: first means for deriving a first signal in accordance with the utterances made by a speaker, second means responsive to the physical forces, including at least one of the forces of physical vibration and acceleration acting on the speaker, which have the effect of altering the characteristics of the voice sounds uttered by the speaker; storage means containing a reference vocabulary in the form of patterned templates of words; and a processing unit receiving the output from the first means and from the second means and performing dynamic adaptation on said templates in accordance with the output of said second means to thereby modify said templates to anticipate the behavior of the speaker\s speech production mechanism as affected by the physical forces detected by said second means; said processing unit comparing the first output signal with the modified templates to produce a second output signal in accordance with the speech sounds uttered by the speaker which are thus compensated, at least in part, by the physical forces acting on the speaker.
