Isan Thai Dialect Speech Corpus with Transcriptions and Demographic Metadata

Audio recordings of Isan (Northeastern Thai) speech are paired with transcriptions and demographic metadata. The dataset, created by typhoon-ai and last updated in November 2025, features spontaneous responses to questions across General and Finance domains. It is designed to support Automatic Speech Recognition, dialect study, and text normalization tasks.

Use Cases

• Train Automatic Speech Recognition (ASR) models based on the described audio recordings and transcriptions.
• Study dialectal variation and sociolinguistics based on the demographic metadata and spontaneous speech samples.
• Develop text normalization tools for the Isan language based on the paired transcriptions.
• Benchmark speech processing models on a low-resource language corpus based on the described structured collection.

Strengths

• Contains rich transcriptions paired with audio recordings, as stated in the description.
• Includes demographic metadata for speakers, which may allow for sociolinguistic analysis.
• Covers two specific content domains (General and Finance), providing topical variety.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale model training.
• Description metadata is limited; actual data quality requires manual inspection after download.
