Tactaid 7

Tactaid VII is a tactile aid which presents coded sound information via seven vibrators. The coded vibratory patterns are unique, consistent and learnable, providing information on a range of speech characteristics, including: voice-voiceless sounds, inflection, intensity, temporal cues, and the crucial first 2 formants that assist in vowel recognition. This information is transmitted through the vibrators in four different ways:

place of vibration

movement of vibration

strength of vibration

duration of vibration

The detailed information available with Tactaid VII makes it ideal for speech production and speechreading training. We especially recommend Tactaid VII for improving speech and language skills in children.
