What does the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) assess?
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) is a standardized tool designed to assess the perceptual characteristics of voice quality in individuals across a broad age range. Clinicians utilize the CAPE-V to systematically evaluate parameters such as roughness, breathiness, strain, pitch, and loudness by analyzing sustained vowels, speech samples, and specific CAPE-V sentences. The main purpose of the instrument is to provide a reliable and valid means to quantify voice deviations, facilitating objective documentation and monitoring of voice disorders severity over time. The assessment is typically conducted using the structured CAPE-V form in combination with auditory perceptual judgments that contribute to the generation of a cape-v score interpretation. This allows speech-language pathologists and otolaryngologists to make informed clinical decisions regarding diagnosis and treatment planning based on measurable acoustic and perceptual data. Comprehensive cape-v instructions ensure consistency in administration and scoring, enhancing interrater reliability and clinical utility.
For which type of patients or populations is the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) intended?
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) is primarily indicated for patients exhibiting symptoms of dysphonia across various etiologies, including neurological, structural, and functional voice disorders. It is particularly useful in clinical contexts where objective documentation of voice quality changes over time is required, such as pre- and post-treatment evaluations in otolaryngology and speech-language pathology. The tool’s structured protocol facilitates standardized auditory-perceptual judgments, enhancing reliability in quantifying parameters like overall severity, roughness, breathiness, and strain. The CAPE-V’s applicability spans a broad age range, allowing for consistent voice assessment in both adult and pediatric populations. Clinicians rely on the CAPE-V form and established score interpretation guidelines to monitor therapeutic progress and support differential diagnosis, making it indispensable in evidence-based voice assessment protocols.
Step-by-Step Explanation of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) consists of six primary items: overall severity, roughness, breathiness, strain, pitch, and loudness, each assessed through sustained vowels, connected speech, and sentences. Clinicians use a visual analog scale, typically 100 mm in length, to rate the magnitude of deviation for each parameter, marking a point along the continuum that best represents the voice quality observed. The evaluation process involves eliciting specific voice samples—sustained vowels /a/ and /i/ for 3-5 seconds, a sentence containing both voiced and voiceless sounds, and spontaneous speech—to ensure comprehensive analysis. Ratings are anchored by descriptive terms at scale endpoints, allowing for nuanced quantification of perceptual attributes. This systematic approach supports the identification and monitoring of voice disorders such as dysphonia and vocal fold paralysis, facilitating targeted intervention planning.

How to interpret the results of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)?
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) test quantifies vocal qualities across six parameters: overall severity, roughness, breathiness, strain, pitch, and loudness, each rated on a 100-mm visual analog scale. Scores below 20 mm typically indicate normal voice function, whereas values exceeding 35 mm suggest moderate to severe dysphonia, often associated with conditions such as vocal fold paralysis or muscle tension dysphonia. For interpretation, clinicians calculate the mean ratings across multiple evaluators to reduce subjective bias, using the formula Mean Score = Σ Scores / Number of Raters. Practically, elevated CAPE-V scores inform healthcare professionals about the severity and type of voice impairment, guiding decisions regarding further diagnostic assessments, therapeutic interventions, or referrals to specialists. This quantitative approach allows for objective monitoring of treatment outcomes in patients with laryngeal pathologies, facilitating tailored management plans based on the degree and nature of vocal deviation.
What scientific evidence supports the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) ?
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was developed in 2001 by a panel of expert clinicians under the auspices of the American Speech-Language-Hearing Association to provide a standardized framework for assessing voice quality. Its validation is supported by studies demonstrating strong interrater and intrarater reliability across various populations, including patients with vocal fold nodules, paralysis, and dysphonia. Quantitative analyses have correlated CAPE-V ratings with acoustic and aerodynamic measures, reinforcing its efficacy as a perceptual tool. Furthermore, longitudinal research has confirmed its sensitivity to treatment-related changes, making it a reliable instrument for both clinical assessment and research in voice disorders.
Diagnostic Accuracy: Sensitivity and Specificity of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) demonstrates variable sensitivity and specificity depending on the clinical context and the rater’s experience. Studies report sensitivity values ranging from approximately 70% to 85%, indicating a moderate to high ability to identify patients with voice disorders. Specificity generally falls between 75% and 90%, reflecting a reliable capacity to exclude individuals without pathological voice characteristics. However, inter-rater reliability can influence these metrics, with expert clinicians achieving higher diagnostic accuracy. Overall, CAPE-V serves as a valuable tool for detecting perceptual deviations in vocal quality, although its performance is optimized when combined with instrumental assessments and structured training of evaluators.
Related Scales or Questionnaires
The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) shares similarities with several other perceptual voice assessment tools, such as the GRBAS scale, the Vocal Handicap Index (VHI), and the Voice-Related Quality of Life (V-RQOL) questionnaire, all of which are detailed and available for download on ClinicalToolsLibrary.com. The GRBAS offers a straightforward rating of grade, roughness, breathiness, asthenia, and strain, providing quick clinical utility but with less granularity compared to the CAPE-V’s visual analog scaling. Questionnaires like the VHI and V-RQOL capture patient-reported impact, complementing the auditory-perceptual focus of CAPE-V but relying on subjective patient insight rather than clinician judgment. In contrast, instrumental assessments such as the Acoustic Voice Quality Index (AVQI) provide objective quantitative data but require specialized equipment and technical expertise, unlike CAPE-V’s clinician-administered format.
