The method and preprocessor enhances the intelligibility of narrowband speech without essentially lengthening the overall time duration of the signal. Both spectral enhancements and variable-rate time-scaling procedures are implemented to improve the salience of initial consonants, particularly the perceptually important formant transitions. Emphasis is transferred from the dominating vowel to the preceding consonant through adaptation of the phoneme timing structure. In a further embodiment, the technique is applied as a preprocessor to a speech coder.

A preferred embodiment of the method for converting text to speech using a computing device having a memory is disclosed. The inventive method comprises examining a text to be spoken to an audience for a specific communications purpose, followed by marking-up the text according to a phonetic markup systems such as the Lessac System pronunciation rules notations. A set of rules to control a speech to text generator based on speech principles, such as Lessac principles. Such rules are of the tide normally implemented on prior art text-to-speech engines, and control the operation of the software and the characteristics of the speech generated by a computer using the software. A computer is used to speak the marked-up text expressively. The step of using a computer to speak the marked-up text expressively is repeated using alternative pronunciations of the selected style of expression where each of the tonal, structural, and consonant energies, have a different balance in the speech, are also spoken to a trained speech practitioners that listened to the spoken speech generated by the computer. The spoken speech generated by the computer is then evaluated for consistency with style criteria and / or expressiveness. And audience is then assembled and the spoken speech generated by the computer is played back to the audience. Audience comprehension of spoken speech generated by the computer is evaluated and correlated to a particular implemented rule or rules, and those rules which resulted relatively high audience comprehension are selected.

A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to differentiate between rapidly presented stimuli. The method utilizes a sequence of phonemes from a confusable pair which are systematically manipulated to make discrimination between the phonemes less difficult or more difficult based on the success of the adult. The manipulation includes processing of the consonant and vowel portions of the phonemes by emphasizing the portions, and / or by stretching the portions. Further processing includes separating the consonant and vowel portions by time intervals. As the adult improves in their auditory processing, the discriminations are made progressively more difficult by reducing the amount of processing to that of normal speech.

PCT No. PCT / GB94 / 00430 Sec. 371 Date Dec. 2, 1996 Sec. 102(e) Date Dec. 2, 1996 PCT Filed Mar. 7, 1994 PCT Pub. No. WO94 / 23423 PCT Pub. Date Oct. 13, 1994Synthetic speech is generated from conventional texts and in particular by converting text in graphemes into a text in phonemes. The grapheme text is analyzed into rimes and onsets, and each word is analyzed from the end so that earlier-occurring segments are at least partially defined by the identification of later-occurring segments. It is a particular feature that an internal string of consonants, i.e., a string of consonants preceded and followed by a vowel, is split into two portions, namely, a second portion which is contained in a database of onsets, and an earlier portion which, together with the preceding vowel or vowels, is contained in a database of rimes.

The present system proposes a technique called the spectro-temporal varying technique, to compute the suppression gain. This method is motivated by the perceptual properties of human auditory system; specifically, that the human ear has higher frequency resolution in the lower frequencies band and less frequency resolution in the higher frequencies, and also that the important speech information in the high frequencies are consonants which usually have random noise spectral shape. A second property of the human auditory system is that the human ear has lower temporal resolution in the lower frequencies and higher temporal resolution in the higher frequencies. Based on that, the system uses a spectro-temporal varying method which introduces the concept of frequency-smoothing by modifying the estimation of the a posteriori SNR. In addition, the system also makes the a priori SNR time-smoothing factor depend on frequency. As a result, the present method has better performance in reducing the amount of musical noise and preserves the naturalness of speech especially in very noisy conditions than do conventional methods.

A device and a method to be used by laryngeally impaired people to improve the naturalness of their speech. An artificial sound creating mechanism which forms a simulated glottal pulse in the vocal tract is utilized. An artificial glottal pulse is compared with the natural spectrum and an inverse filter is generated to provide an output signal which would better reproduce natural sound. A digital signal processor introduces a variation of pitch based on an algorithm developed for this purpose; i.e. creating prosody. The algorithm uses primarily the relative amplitude of the speech signal and the rise and fall rates of the amplitude as a basis for setting the frequency of the speech. The invention also clarifies speech of laryngectomees by sensing the presence of consonants in the speech and appropriately amplifying them with respect to the vowel sounds.

A technique for stylus-based syllabic input that is fast and easy and does not require any additional hardware and can be deployed on a handheld device is described. In one example embodiment, this is accomplished by writing a base syllabic character consisting of a vowels or consonant in a writing area. One or more modifiers that are displayed as icons substantially around the writing area of a syllabic level user interface are then selected to form a desired syllabic character. The one or more modifiers are arranged at familiar / natural positions around the base character's writing area to facilitate entry / selection of modifiers and to reduce eye movement / cognitive load on the user. The syllabic characters are then accumulated locally until a desired word is formed, to reduce visual disconnect between the input interface and the end application, and to provide context for formation of the desired word. Further, one or more hypothesis words are then presented to speed up the formation and inputting of a desired word. The formed desired word is then cleared from the display area and sent to an application display area by tapping a space button provided in the syllabic character input user interface.

The invention relates to a Chinese multi-keyword fuzzy sort encryption text search method based on local sensitive hash. After Chinese keywords are converted into the corresponding Chinese phonetic alphabet strings, the Chinese phonetic alphabet strings are segmented based on consonants, vowels, tones, and unigram; a vector generation algorithm of three types of Chinese keywords is designed, the Chinese phonetic alphabet strings are mapped to keyword vector; fuzzy matching of keywords is achieved by utilizing the attributes of locally sensitive hash and bloom filters. The encryption index of the document adopts the method of one document corresponding only to one bloom filter, at the addition of a new document (or the deletion of an old document), the encryption index of an original data set does not need to be changed, only the encryption index of the new document needs to be built (or the encryption index of the old document is deleted), and dynamic updating of the document can be achieved. A domain weighted scoring method is introduced into the method in order to improve the accuracy of the sort results, the Euclidean distance between the keyword vectors, the weight of keyword frequency and domain weighted scoring are combined, more accurate three-factor sorting is achieved, and documents which meet user needs more are returned.
