Agri STT Benchmarking Dataset

10,808 farmer voice queries in Hindi, Telugu and Odia, with reference transcripts, for benchmarking automatic speech recognition in agricultural contexts. The audio is included in this repository.

Every recording is a smallholder farmer speaking a question to Farmer.Chat, an AI advisory service run by Digital Green. Reference transcripts were produced by human annotators. Nothing here is read from a script or recorded in a studio, so the audio carries the noise, overlap and dialect of real field conditions.

Contents

• audio/ - 10,808 OGG files, numbered 00001.ogg upward and split across subdirectories of 1,000 (audio/000/, audio/001/, and so on). Use the Filename column rather than assembling the path yourself.
• benchmark.parquet - all three languages in one table
• Agri_Benchmark_Hindi.csv - Hindi only, 4,576 rows
• Agri_Benchmark_Telugu.csv - Telugu only, 4,027 rows
• Agri_Benchmark_Oriya.csv - Odia only, 2,205 rows

Column	Description

Usage

from datasets import load_dataset
from huggingface_hub import snapshot_download

ds = load_dataset("DigiGreen/Agri_STT_Benchmarking_Dataset", split="train")
root = snapshot_download("DigiGreen/Agri_STT_Benchmarking_Dataset", repo_type="dataset")

row = ds[0]
audio_path = f'{root}/{row["Filename"]}'
print(row["Language"], row["reference"])

Privacy

Earlier versions of this dataset delivered the audio as links to a cloud storage bucket, and the filename in each link carried an internal message identifier. Both are gone. The audio now ships from this repository under sequential filenames that carry no information about the speaker, the conversation, or the original record. The Filename column keeps its name and now holds a path inside this repository.

Every reference transcript was screened for personal information by two language models independently, the second reviewing everything the first flagged plus a blind sample of what it cleared. 56 recordings were removed because the speech contained personal information: a person's name, a village or landmark specific enough to narrow down a household, a phone or ID number, money tied to a named person, a medical detail, or a private domestic matter.

Reason for removal	Recordings
place name	31
person name	16
health	9
household	6
money	1
phone	1

Two limits are worth stating rather than leaving implied. The screening read the transcripts, not the audio, and a recording holds everything its transcript holds plus whatever the annotator left out. And a voice is biometric whatever the words are: these are real people, identifiable to anyone who knows them, which is the nature of a speech corpus rather than a defect in this one. Treat the recordings as personal data. If you find something that should not be here, please open a discussion and it will be removed.

Some recordings also capture speech that is not the farmer's question, such as a second person in the room or a field agent explaining the app. Where that speech carried nothing identifying it was left in, because it is part of the real acoustic conditions this benchmark is meant to measure. Expect it when scoring against the references.

Changelog

July 2026. Audio moved into the repository as audio/00001.ogg upward; the Filename column now holds that path instead of a storage URL. Added benchmark.parquet covering all three languages. Screened every transcript for personal information and removed 56 recordings.
