speech intelligibility
Noun: - The degree to which spoken language can be understood by a listener: Speech intelligibility refers to the clarity and comprehensibility of spoken words, often quantitatively assessed, particularly in challenging acoustic environments like noise or with signal distortion.
Speech intelligibility is a technical term used primarily in fields like acoustics, audiology, telecommunications, and linguistics. It describes a measurable quality of communication. - It is often discussed as a percentage (e.g., 95% intelligibility). - It is a critical factor in designing sound systems, hearing aids, and communication devices. - It is evaluated under specific conditions, such as in the presence of background noise or through a particular transmission channel.
- The primary goal of the new hearing aid design was to improve speech intelligibility for users in crowded restaurants.
- Audio engineers tested the speech intelligibility of the public address system in the train station.
- A high signal-to-noise ratio is essential for optimal speech intelligibility over the radio.
- The study measured the speech intelligibility of synthesized voices compared to human speech.
- "Speech Intelligibility Index (SII)": A standardized method for calculating the predicted intelligibility of speech based on acoustic measurements.
- "Speech Transmission Index (STI)": A measure used to assess the quality of speech transmission in rooms or through electro-acoustic systems, directly related to intelligibility.
- Intelligibility (noun): The general quality of being understandable or comprehensible. (e.g., the intelligibility of the ancient manuscript).
- Intelligible (adjective): Able to be understood. (e.g., The recording was barely intelligible).
- Clarity (of speech)
- Comprehensibility (of speech)
- Audibility (Note: specifically refers to the ability to be heard, which is a prerequisite for, but not the same as, intelligibility, which is the ability to be understood.)
- "Word recognition score": In audiology, a common test to measure speech intelligibility by presenting lists of words to a listener.
- "Lombard effect": The involuntary tendency of speakers to increase their vocal effort (e.g., louder speech, altered pitch) in noisy environments to maintain speech intelligibility.

the intelligibility of speech (usually measured in the presence of noise or distortion)
