PhonoLex Documentation¶

PhonoLex is a comprehensive phonological analysis and word list generation tool designed for speech-language pathologists, linguists, researchers, and educators.

Features¶

Custom Word Lists - Pattern matching with 35 filterable properties across 9 categories
Text Analysis - Analyze passages with interactive highlighting and aggregate percentile statistics
Contrastive Sets - Research-based phonological interventions: minimal pairs, maximal opposition, and multiple opposition
Sound Similarity - Find similar words with adjustable onset, nucleus, and coda weights
Lookup - Word lookup, phoneme features, phoneme comparison, feature-based phoneme search, and cognitive associations (USF, ECCC, SPP, MEN, SimLex, WordSim)

Data & Methodology¶

PhonoLex consolidates 15 peer-reviewed research datasets into a single platform for phonological analysis:

44,011 English words with 35 filterable psycholinguistic properties
68,000+ word associations across 6 relationship types (free association, semantic relatedness, perceptual confusability, semantic priming, similarity)
Learned phoneme feature vectors via Bayesian inference (26 articulatory features)
35 filterable properties across 9 categories (phonological, phonotactic, lexical, semantic, affective, cognitive, sensorimotor, morphological)
Phoneme-sequence similarity using soft Levenshtein distance on learned feature vectors

Architecture¶

PhonoLex v4.1 uses a modern edge-computing architecture: a Hono backend on Cloudflare Workers with a D1 database, and a React frontend. Data from 15 research datasets is consolidated and served via a REST API.

API¶

PhonoLex provides a public REST API for programmatic access. Interactive documentation is available at /docs (Swagger UI) and /redoc (ReDoc).

PhonoLex uses a split license: Apache 2.0 for open packages (data, features, web) and proprietary for the constraint engine and governed generation platform. See License for details.
