An electric field generated by another electric field communications apparatus reaches electric field sensor ES. Electric field sensor ES outputs an electric signal in response to the changes in the electric field. The electric field that reaches electric field sensor ES enters a return path of the electric field communications apparatus that is a source of the electric field. By locating electric field sensor ES between receiver main electrode ERB and receiver return electrode ERG, electric field intensity at the location where electric field sensor ES is positioned. Therefore, sensitivity of the changes in electric field for electric field communications apparatus TRX can be improved.

A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.

An object of the present invention is to enable optimal clustering for many types of noise data and to improve the accuracy of estimation of a speech model sequence of input speech. Noise is added to speech in accordance with noise-to-signal ratio conditions to generate noise-added speech (step S), the mean value of speech cepstral is subtracted from the generated, noise-added speech (step), a Gaussian distribution model of each piece of noise-added speech is created (step S), the likelihoods of the pieces of noise-added speech are calculated to generate a likelihood matrix (step S) to obtain a clustering result. An optimum model is selected (step S) and linear transformation is performed to provide a maximized likelihood (step S). Because noise-added speech is consistently used both in clustering and model learning, clustering for many types of noise data and an accurate estimation of a speech model sequence can be achieved.

Information relating to an amount of muscle activity is extracted from a myo-electrical signal by activity amount information extraction means, and information recognition is performed by activity amount information recognition means using the information relating to the amount of muscle activity of a speaker. There is a prescribed correspondence relationship between the amount of muscle activity of a speaker and a phoneme uttered by a speaker, so the content of an utterance can be recognized with a high recognition rate by information recognition using information relating to an amount of muscle activity.

An object of the present invention is to facilitate dealing with noisy speech with varying SNR and save calculation costs by generating a speech model with a single-tree-structure and using the model for speech recognition. Every piece of noise data stored in a noise database is used under every SNR condition to calculate the distance between all noise models with the SNR conditions and the noise-added speech is clustered. Based on the result of the clustering, a single-tree-structure model space into which the noise and SNR are integrated is generated (steps Sto S). At a noise extraction step (step S), inputted noisy speech to be recognized is analyzed to extract a feature parameter string and the likelihoods of HMMs are compared one another to select an optimum model from the tree-structure noisy speech model space (step S). Linear transformation is applied to the selected noisy speech model space so that the likelihood is maximized (step S).
