Speech processing in voice-hearers: Bridging the gap between empirical research and clinical implications

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Neuroscience

Background:

• Auditory verbal hallucinations (AVH) are associated with speech processing difficulties.
• These challenges persist even when not actively hearing voices.
• Symptom severity can worsen speech processing deficits.

Purpose of the Study:

• To present empirical findings on external speech processing in voice-hearers.
• To inform healthcare professionals about these challenges.
• To improve communication strategies for patients experiencing AVH.

Main Methods:

• Review of empirical research on speech processing in individuals who hear voices.
• Analysis of findings related to external speech perception and comprehension.
• Synthesis of evidence to guide clinical practice.

Main Results:

• Voice-hearers exhibit significant difficulties in processing spoken language.
• Speech processing deficits are a core feature, not solely tied to active hallucinations.
• Acute symptomology can exacerbate these auditory processing impairments.

Conclusions:

• Enhanced understanding of speech processing deficits is crucial for effective patient communication.
• Healthcare professionals can benefit from this knowledge to tailor communication approaches.
• Addressing these specific challenges may lead to better therapeutic alliances and outcomes.
