Transcribe Ghanaian-language speech to text

POST 
/v2/language/transcribe

Converts spoken audio in a Ghanaian language to text via the GhanaNLP Khaya ASR API (ISO 639-3 codes; languages limited to those with ASR support). Send the raw audio bytes as the request body with an appropriate Content-Type (browser MediaRecorder webm/opus and Telegram ogg/opus both work). English is out of scope — browsers handle English natively via the Web Speech API.

Public but tightly throttled (speech recognition is metered and uncacheable). Returns 503 when not configured or quota-exhausted.
