Pronunciation Coach 3D

Pronunciation Coach 3D

Without a good understanding of how to pronounce the individual sounds of a language, it can be difficult to speak words clearly. Pronunciation Coach 3D uses state-of-the-art computer animation and 3D modelling techniques to illustrate how to pronounce all of the sounds in the English language, and how to combine these sounds to pronounce any word or sentence.

Key features:

  • Animated 3D model shows you how to pronounce any sound, word or sentence.
  • Records your pronunciation and lets you compare it to an example.
  • Scores your pronunciation using automated speech recognition.
  • Contains a 40 lesson English pronunciation guide.

3D pronunciation model

The animated 3D pronunciation model consists of the lips, teeth, tongue, lower jaw, hard palate and soft palate. The transparency of these articulators can be adjusted to reveal hidden structures, and the model can be rotated 360°. The appearance of the model can also be viewed in photorealistic or stylized modes.

For accuracy, a technique known as electropalatography was used to create many of the tongue shapes featured in the 3D pronunciation model.

Creating 3D pronunciation models

To create a 3D pronunciation model, simply type in any word or sentence. Alternatively, click on the International Phonetic Alphabet (IPA) symbols to learn individual sounds. Once the model has been created, a waveform providing information on timing, pitch and speech intensity is displayed.

The media controls enable you to play, pause and step through the model one phoneme at a time.

Recording and scoring pronunciation

Pronunciation Coach 3D lets you record your speech so you can compare it with the pronunciation model. In addition, speech recognition provides valuable feedback on your speech intelligibility.

Speech intelligibility is a measure of how easily speech can be understood and is expressed as a percentage. The speech intelligibility scores are categorised as follows:

Intelligibility description Intelligibility score
Unintelligible 0%
Poor 10% - 30%
Fair 30% - 50%
Good 50% - 75%
Excellent 75% - 100%
