Speaktellcount

Speaktellcount is a theoretical metric used in the study of spoken communication to quantify how efficiently a speaker conveys core information within a given time frame. The term combines elements of speaking, telling, and counting, and it is primarily discussed in niche literature on speech analytics and communication theory. It is not a widely standardized term and formal definitions vary among authors.

Definition and measurement

Speaktellcount (STC) is defined as the number of independently verifiable propositions communicated in a segment of speech divided by the duration of that segment, typically measured in minutes. In practice, a proposition is a distinct factual claim, outcome, or instruction that could be verified or refuted. The calculation can be expressed as STC = N / D, where N is the count of propositions and D is time in minutes. Because identifying propositions can be subjective, researchers often adopt explicit criteria or use coder-based annotation to improve consistency.

Interpretation

Higher STC values imply more concise, information-dense, or directive speech, whereas lower values suggest longer, more repetitive, or filler-heavy delivery. The metric is intended to aid comparisons across speakers, modalities, or textual forms (for example, lectures versus tutorials) and to inform practices in instruction, storytelling, or voice-interface design.

History and usage

Speaktellcount arose as a descriptive tool in discussions about communicative efficiency. It has not achieved broad adoption or formal standardization, and it is often presented alongside related measures such as information density, lexical density, and speech rate.

Limitations

Quantifying propositions is inherently subjective, and outcomes can depend on audience prior knowledge and context. STC should be used cautiously and complemented by qualitative assessment when evaluating communication quality.
