Visual texture is a way of representing timber, but we found it to be weak. On the other hand, linguistic features have a more direct relationship to kinetic forms. Linguistic features work at the level of syllables, words, and sentences. They are the metrical structure, rhythmic and intonational aspects of language. The most important linguistic features are pitch, loudness, and tempo or speed of delivery.
Pitch is defined as different levels of tones in spoken communication.
For instance, the difference between a falling and a rising pitch pattern might be the difference between a statement and a question. In our experiments, we have found that kinetic typography can convey pitch differences by using large upward or downward movements across the display area. These are used to convey gross differences of meaning, such as the increased volume heard with anger, or contrasts heard on different syllables in a word. These changes in loudness can be represented in kinetic typography. For example, a phrase that is stressed in a sentence might be represented by a weight or size change.
