Speech Referral Guidelines

​Warning Signs that should trigger a referral to an SLP at any age:

  • Shows decline in ability to be understood by family, friends, and/or caregivers in the expression of basic needs, preferences, and feelings

  • Speech is usually slurred; difficulty controlling respiration for speech; abnormal loudness, rhythm, or vocal quality

  • Produces no meaningful words or sounds that are understood only by family

  • Speaks loudly in high pitched voice with frequent distortion, omission, and substitution of sounds

  • Exhibits difficulty learning sounds to form words; may sound nasal, strangled and/or breathy

  • Sound errors are prevalent but variable (i.e., "dog" could be produced "dog," "tog," "gog," "god" by same child)

  • Varies from rarely being able to produce sounds to ongoing speech that is rarely understood, or speech that is usually understood with frequent sound errors

  • Unaware of sound variations or exhibits varying degrees of frustration and/or anxiety regarding inability to "control speech"

  • Cannot produce movements for sound production or sounds are produced without voice (whispered speech)
