ARTPARK-IISc/Vaani-LID_v0

Model Card for Model ID

Indic Spoken Language Classifier supporting 42 languages.

Model Details

The model consists of a whisper-large-v3-turbo encoder followed by a pooled-attention module and finally a linear classifier layer. Trained end-to-end on ARTPARK-IISc/Vaani dataset, capable of classifying 42 Indic languages. The list of supported languages include:

How to Get Started with the Model

from transformers import pipeline

pipe = pipeline(
    "audio-classification",
    model="ARTPARK-IISc/Vaani-LID_v0",
    trust_remote_code=True,
    # device=-1 # uncomment this line to run on cpu
)

out = pipe("path/to/16kHz/mono-channel/wav/file")
print(out)
