Voice analysis
Speech provides a rich source of information about language, cognition, motor speech and emotional expression. Our voice technology enables researchers and trial sponsors to collect standardised speech samples and turn them into quantitative acoustic and linguistic measures.
Enhancing your study with voice biomarkers
Changes in the brain and nervous system can have dramatic effects on speech and language, making voice biomarkers a valuable tool for assessing and monitoring neurological and psychiatric disorders.
Speech contains information in both what is said — the words, meaning and structure of language — and how it is said — including fluency, timing, rhythm and other characteristics of speech production.
Analysing these features through voice biomarkers provides additional information alongside conventional cognitive and clinical assessments.
Analysing voice to assess neurological change
Automated speech
recognition (ASR)
Real time, automated scoring for immediate feedback. Adaptive tasks help to provide richer data while improving the user experience.
Up to 98%
accuracy
Scientifically validated, our verbal tasks are short and automated for a comfortable user experience while maintaining a high scoring accuracy.
Natural language usage
Open-ended conversational tasks and measures characterise both acoustic and linguistic changes such as word finding difficulty, coherence, and language fluency.
Unrivalled expertise in voice-based cognitive assessments from Cambridge Cognition and Winterlight Labs
Our voice analysis platform can be used alongside tasks in our CANTAB® cognitive assessment battery to provide deep and diverse data, available across a range of devices, including web-based browsers, tablets and smartphones.
Highly scalable
Faster administration
Improved user experience
Measuring a full range of cognitive abilities, our voice assessments are highly sensitive, enabling you to identify changes faster.
