SraVaani-1.0 — unmodified mirror

This is a byte-for-byte mirror of ARTPARK-IISc/SraVaani-1.0.

All credit belongs to the original authors at ARTPARK and the Indian Institute of Science. No weights, code or configuration have been modified.

Why this mirror exists

It is used by SraVaani Flow, an offline dictation app, so that people evaluating the app on a shared machine can install it without each needing their own Hugging Face account and access token.

The original repository is gated (auto-approved on accepting the terms). This mirror is redistributed under the MIT licence that the original release grants. If you are using the model for your own work, please use the official repository — it is the canonical source, it is where updates land, and the authors ask that users share contact details so they can gauge adoption:

If the ARTPARK-IISc authors would prefer this mirror not exist, contact vaanicontact@gmail.com or open a discussion here and it will be taken down.

About the model

A ~430M parameter FastConformer ASR model with a hybrid TDT-CTC decoder, supporting 65 Indian languages and dialects. It ships as an exported TorchScript graph, so inference needs only torch, transformers and sentencepiece — no NeMo toolkit.

Files

File	Size	Purpose
model-asr.fp16.ts	867 MB	TorchScript encoder + decoder/joint graph, fp16
tokenizer.model	318 KB	SentencePiece vocabulary (5000 tokens)
preproc.pt	132 KB	Mel filterbank, STFT window, feature parameters
config.json, model_meta.json	—	Model configuration
modeling_sravaani.py	—	HF wrapper (needs trust_remote_code=True)
configuration_sravaani.py, processing_sravaani.py	—	Config and processor

Usage

import torch
from transformers import AutoModel

model = AutoModel.from_pretrained(
    "SharadhNaiduTrains/sravaani-flow-model",
    trust_remote_code=True,
    dtype=torch.float16,
).to("cuda").eval()

# note the list: a bare ndarray would be iterated element-wise
print(model.transcribe(["sample.wav"])[0])
