About

What kosp2e-asr-ko is

This is the ESPnet2 recipe for the KoSP2E (Korean Speech Perception and Production Experiment) dataset.


Overview

The KoSP2E dataset is a large-scale Korean speech corpus designed for speech perception and production experiments. This recipe provides a full ASR pipeline using ESPnet2 with both Transformer and Conformer architectures.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys kosp2e-asr-ko for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (kosp2e-asr-ko below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -F model="kosp2e-asr-ko" -F file=@audio.mp3
