An aid for speech therapy comprising a chart having a series of time frames of equal time intervals. Each of the time frames has an illustration of the human mouth to pictorially display the lips, tongue and jaw positions of the mouth in making a sound, word or phrase alphabetically displayed in the time frames. A sound reproducing device may also be provided to audibly reproduce the sound, word or phrase which is alphabetically displayed.

A speech therapy device for providing a means for the treatment of speech and swallowing problems and disorders comprising a sheet having first and second surfaces with a centrally-affixed means for providing direct visual feedback, as well as instructions, guidelines and indicia placed strategically therearound for practicing basic oral exercise drills. The preferred visual feedback means is a mirror, particularly one comprised of an acrylic material. The sheet may be either a single flat sheet or folio prepared from a folded single sheet or multiple sheets.

This speech training system enables students to rapidly acquire and perfect their pronunciation of English phrases by speaking along with videos presenting English phrases accompanied by conventionally-spelled English text and characters representing the correct mouth positions. Students learn the mouth positions, then listen to a phrase, speak it simultaneously following the mouth position characters, and read the text. Students of this method can compare their mouth movements to a model of standard pronunciation visually and auditorily. Students of English thus have a more reliable audiovisual means of learning and practicing correct English pronunciation.

A structural graphic display has one or more first generally transparent surfaces with reversed images superposed thereon juxtaposed to a reflective surface such that the reversed image may be viewed as a reflection in the reflective surface. The display may be either purely an ornamental device, or may be utilized in lamps, desk accessories, greeting cards, or clocks as disclosed herein.

A system and method for determining from continuous speech, the instantaneous values of a set of articulatory parameters. The continuous speech data is a sequence of spectral profiles obtained by spectrally sampling continuous speech. The spectral samples are presented in sequence to a plurality of class transforms, each establishing a respective speech phoneme class which includes plurality of speech phoneme having similar spectral and articulatory characteristics. Each class transform converts a speech segment included in its class and contained in a spectral sample into a predetermined set of articulatory parameter values. A class-discriminating transform operates in parallel with the class transforms to produce a set of probability values, each indicating the probability that the spectral sample being transformed represents a phoneme in a respective speech phoneme class. An array of multipliers adjusts the predetermined values of the sets produced by the class transforms by multiplying the values of each set by the probability value produced for that set by the class-discriminating transform. The adjusted articulatory parameter value sets are combined by adding corresponding elements to produce a set of adjusted articulatory parameter values indicative of an articulatory tract configuration appropriate for producing the sampled speech.
