Components of Language01:24

Components of Language

499
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Perception of Sound Waves01:01

Perception of Sound Waves

4.8K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

Auditory Pathway01:15

Auditory Pathway

6.0K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

Auditory Perception01:17

Auditory Perception

650
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Area of Science:

  • Audiology and Speech Sciences
  • Linguistics

Background:

  • Speech intelligibility testing is crucial for assessing hearing abilities.
  • Existing sentence lists may require updates for clarity and relevance.
  • Standardized protocols are needed for accurate speech perception assessment.

Purpose of the Study:

  • To adapt a list of sentences for a speech intelligibility test.
  • To create a free speech perception protocol for speech-language therapists.
  • To aid in standardizing assessment for individuals with normal hearing and hearing loss.

Main Methods:

  • Analysis and partial update of 200 phonetically balanced sentences.
  • Review by 60 linguistics and speech/hearing specialists using an online questionnaire.
  • Evaluation of sentence familiarity, meaning, predictability, and adherence to construction criteria.

Main Results:

  • High inter-reviewer agreement on sentence parameters.
  • 71 sentences recommended for modification, primarily for predictability.
  • 28 additional sentences adjusted, often due to the presence of proper names.

Conclusions:

  • Successfully adapted sentence list for a speech perception protocol.
  • Provides a free resource for speech-language therapists.
  • Aims to standardize speech intelligibility assessment in Brazilian Portuguese.
