Language Sample Analysis Is the Gold Standard. The Problem Is Time.

Every SLP knows that naturalistic language sampling provides the most ecologically valid picture of a child's communication. It captures how children actually talk, not how they perform on decontextualized test items.

The problem has never been clinical value. The problem is that manual transcription, morphological coding, and metric calculation take 5+ hours per sample. With caseloads of 50-80+ students, most SLPs simply can't afford the time.

EASI solves this by automating the mechanical work while keeping the clinician central to every decision. You still evaluate. You still interpret. You still make the clinical call. EASI handles the transcription, the speaker separation, the metric calculations, and the report generation.

The result: comprehensive language sample analysis in 15-30 minutes instead of 5+ hours.

Clinical Metrics Calculated Automatically

All metrics are derived exclusively from clinician-attested data. Every value is editable. Standard scores use age-appropriate norms.

MLU

Mean Length of Utterance

Automatically calculated from clinician-attested transcription. Standard scores generated using age-appropriate norms with confidence ratings.

IPSYN

Index of Productive Syntax

Syntactic complexity scoring across noun phrase, verb phrase, question/negation, and sentence structure categories. Scored against developmental expectations.

NDW

Number of Different Words

Vocabulary diversity measurement from natural speech. Captures lexical variety in context rather than isolated word retrieval.

PCC

Percent Consonants Correct

Derived from IPA transcription after clinician review and attestation. Includes intelligibility scoring and phonological pattern analysis.

VOT

Voice Onset Time

Acoustic analysis of voicing contrasts. Provides objective data on speech motor timing that complements perceptual judgments.

Intelligibility

Intelligibility Scoring

Hybrid acoustic and transcription-based intelligibility measurement. Blends computational analysis with clinician-attested data for reliable scoring.

From Recording to Report in 15-30 Minutes

Draft, Review, Attest, Score. Nothing is scored until you say so.

01

Record a Natural Sample

Use any device to record during play-based assessment, conversation, or structured tasks. EASI provides customizable visual prompts to elicit natural communication.

02

Automatic Transcription & Diarization

EASI transcribes the recording with 98-99% accuracy and automatically separates speakers. A full IPA rendering is generated alongside the English transcription.

03

Clinician Review & Attestation

You review the transcription and IPA side by side, editing any word or phoneme. Nothing is scored until you explicitly attest the output. Raw AI output is never used as a fallback.

04

Scores & Reports in Minutes

Standard scores, percentile rankings, state eligibility criteria, and professional reports are generated from your attested data. All metrics are editable. CPT codes included.
