A student examines a visible speech chart in a linguistics textbook.

Definition

1. Noun:
   • A system for representing speech sounds visually: "visible speech" refers to a method of displaying the acoustic characteristics of spoken language in a visual format, such as a spectrogram that shows frequency, intensity, and time.
   • A historical phonetic alphabet: "visible speech" also specifically denotes a written phonetic alphabet invented by Alexander Melville Bell in the 19th century, designed to represent the positions of the speech organs for each sound.

Examples of Usage

• Noun:
  • The linguist used visible speech to analyze the vowel formants in the recording. (The linguist used a spectrographic representation to analyze the vowel formants.)
  • Melville Bell's system of visible speech was a precursor to modern phonetic notation. (Melville Bell's phonetic alphabet was a forerunner to contemporary systems.)

Advanced Usage

• As a tool in speech science and pathology: "Visible speech" spectrograms are used to study, diagnose, and treat speech disorders by making the acoustic properties of speech observable.
  • The speech therapist reviewed the visible speech patterns to assess the client's articulation.

Variants and Related Words

• Spectrogram (n): A visual representation of the spectrum of frequencies in a sound as they vary with time.
  • The spectrogram provided a detailed visible speech analysis.
• Phonetic alphabet (n): A set of symbols used to represent the sounds of speech.
  • The International Phonetic Alphabet (IPA) is a more widely used system than Bell's original visible speech.

Synonyms

Related Phrases
