Voice and Resonance
  • Resonance/Voice/Fluency
  • 9.0 Role Identification/Assessment and
    Treatment/Management of individuals at risk for
    resonance, voice, and/or fluency disorders. This
    includes knowledge and skills related to
  • Current research on preferred practice patterns
    in the identification/assessment and
    treatment/management of resonance, voice and/or
    fluency disorders.

Voice and Resonance
  • Resonance/Voice/Fluency
  • Community standards of typical resonance, voice,
    and/or fluency patterns.
  • Application of the standards of the
    client's/patient's speech/communication community
    for dismissal/discharge criteria.

5
Voice and Resonance
  • Areas of consideration for CLD Populations
  • In order to fully understand the impact of a
    communication disorder on a persons life,
    assessment and treatment of communication
    disorders must be done in the context of the
    patients language and culture
