iSpeech Pro stimulator, which includes all the main functions of the previous model and has the following significant changes that expand its capabilities: The design includes a vertical front panel, which greatly improves the perception of visual display by students. As a result, it became possible to use the device for collective training. Along the light scales "exhalation/voice Intensity" and "pitch" are implemented movable markers that allow the specialist (teacher) to specify certain control points on the scale. If the scale is "the intensity of the exhale/voice", the teacher will use the reference point of the marker to give the job to the student in the process of working on silo exhalation or volume of the voice. In the case of using the scale of "pitch" movement of the light marker allows the teacher to put before the student such tasks: to what point it should bring the height of the voice, from what level to raise the height, in which the target point "fall" voice and others.
