OpenSLR-65 – Tamil Transcribed Speech

Source: https://www.openslr.org/65/

This dataset contains transcribed high-quality audio of Tamil sentences recorded by volunteers. It is part of the OpenSLR collection of free speech resources for low-resource languages.

The data was collected via the Appen (formerly Figure Eight / CrowdFlower) crowdsourcing platform and is intended for use in training automatic speech recognition (ASR) and text-to-speech (TTS) systems.

Data Collection

Volunteers were asked to read Tamil sentences displayed on their screen and record themselves. Quality control was performed to ensure accurate transcriptions and clean audio.

Usage

Load the Dataset

from datasets import load_dataset

# Load full dataset
dataset = load_dataset("deepdml/openslr65-tamil")
train_data = dataset["train"]
# train_data = load_dataset("deepdml/openslr65-tamil", split="train")

Inspect a Sample

sample = train_data[0]

print(sample)
# {
#   'file_id':    'tag_09162_01279273055',
#   'audio':      {'array': array([...], dtype=float32)},
#   'transcription': 'அவர்களின் படங்களின் டீஸருக்கு கிடைக்கும் வரவேற்பு அபிரிதமாக உள்ளது',

import IPython.display as ipd
ipd.Audio(sample["audio"]["array"], rate=sample["audio"]["sampling_rate"])

Filter by Duration

# Keep only utterances between 2 and 15 seconds
filtered = train_data.filter(lambda x: 2.0 <= x["duration"] <= 15.0)
