MahtaFetrat/Mana-TTS

ManaTTS-Persian-Speech-Dataset

ManaTTS is the largest publicly available single-speaker Persian corpus, comprising over 114 hours of high-quality audio (sampled at 44.1 kHz). Released under the permissive CC-0 license, this dataset is freely usable for both educational and commercial purposes.

Collected from Nasl-e-Mana magazine, the dataset covers a diverse range of topics, making it ideal for training robust text-to-speech (TTS) models. The release includes a fully transparent, open-source pipeline for data collection and processing, featuring tools for audio segmentation and forced alignment. For the full codebase, visit the ManaTTS GitHub repository.

Dataset Columns

Column Name	Description
file_name	Unique identifier for the audio file.
transcript	Ground-truth text transcription of the audio chunk.
duration	Duration of the audio chunk (in seconds).
match_quality	Quality of alignment between the approximate transcript and ground truth (HIGH or MIDDLE). Reflects confidence in transcript accuracy (see paper for details).
hypothesis	Approximate transcript used to search for the ground-truth text.
CER	Character Error Rate between the hypothesis and accepted transcript.
search_type	Indicates whether the transcript was matched continuously in the source text (type 1) or with gaps (type 2).
ASRs	Ordered list of ASRs used until a match was found.
audio	Audio file as a numerical array.
sample_rate	Sampling rate of the audio file (44.1 kHz).

Usage

Python (Hugging Face)

First install the required package:

pip install datasets

Then load the data:

from datasets import load_dataset

# Load a specific partition (e.g., part 001)
dataset = load_dataset("MahtaFetrat/Mana-TTS", 
                      data_files="dataset/dataset_part_001.parquet", 
                      split="train")

# Inspect the data
print(dataset)
print(dataset[0])  # View first sample

Command Line (wget)

Download individual files directly:

# Download single file (e.g., part 001)
wget https://huggingface.co/datasets/MahtaFetrat/Mana-TTS/resolve/main/dataset/dataset_part_001.parquet
