TELL Mobile - Voice Biomarker Assessment Platform

TELL (Technology for Early Language Learning) Mobile is a clinical-grade voice
and language assessment application designed for healthcare professionals,
researchers, and participants in speech and cognitive evaluation programs.
Transform your smartphone into a powerful tool for capturing vocal biomarkers
and tracking language development through scientifically validated assessment
protocols.

What is TELL Mobile?

TELL Mobile enables participants to complete speech and language assessments
remotely or in clinical settings. The app guides users through structured
tasks—from picture descriptions to conversational recordings—capturing
high-quality audio for advanced analysis. Each recording is processed through
cutting-edge acoustic and linguistic feature extraction pipelines, generating
objective biomarkers that support clinical decision-making and research
insights.

Scientific Foundation

TELL is built on peer-reviewed research in speech biomarkers and computational
linguistics. The platform extracts dozens of validated acoustic and
linguistic features including:
• Speech timing and rhythm patterns
• Vocal quality and prosody
• Lexical diversity and complexity
• Semantic coherence
• Sentiment and emotional tone
• Fluency and articulation metrics

These biomarkers support assessment of language development, cognitive
function, neurological conditions, and therapeutic progress.

Requirements

• Android device (version 8.0 or higher recommended)
• Microphone access for audio recording
• Internet connection for data upload (recordings can be made offline)
• Valid participant credentials provided by your clinical or research
organization
