🌟 Overview

Quranic Recitation Dataset (Word-by-Word Sync) is a highly optimized, production-ready dataset containing high-quality audio recitations of the Holy Quran synchronized at the word-by-word level.

This dataset features 135 world-renowned reciters, with every Surah (114 chapters) mapped precisely to millisecond-accurate word timestamps. It is designed for modern Islamic mobile and web applications — served via a Cloudflare Edge CDN with native range-request support for instant audio streaming and seeking.

🚀 Key Features

• 135 Reciters × 114 Surahs — totaling 15,390 audio files with matching timing data.
• Optimized Audio — Mono-channel, 16kHz, 32kbps .opus format. Exceptional clarity at ultra-low bandwidth.
• Per-Surah Architecture — Each surah is a single .opus file. Seek to any ayah using the timing data — no need to download individual ayah files.
• Protocol Buffer Timing — Binary .pb timing files are ~33% smaller than JSON and parse instantly in any language.
• Cloudflare Edge CDN — Files are served from cdn.mualim.app with edge caching, CORS, and native HTTP 206 Partial Content for mobile audio seeking.
• Word-Level Accuracy — Timestamps map to standard Uthmani script word indices, enabling karaoke-style highlighting.

Direct HuggingFace Fallback

If the CDN is unavailable, you can fetch directly from HuggingFace:

https://huggingface.co/datasets/zaibihassan/Quranic-Recitation-Data/resolve/main/{Folder Name}/{Surah}/{File}

Note: Folder names on HuggingFace contain spaces and special characters (e.g., Mishari Rashid Al Afasy (Murattal)). The CDN slug mapping handles this automatically.

📂 Dataset Structure

The dataset is organized by Reciter Folder → Surah Number (001–114).

Each surah folder contains two files:

1. {surah}.opus — Per-surah audio file (full surah in one file)
2. {surah}.pb — Protocol Buffer word-by-word timing data

├── Abdul Basit Abdul Samad (Mujawwad)/
│   ├── 001/
│   │   ├── 001.opus    (Full Surah Al-Fatihah audio)
│   │   └── 001.pb      (Word timestamps for all ayahs)

⏱️ Timing Data Schema (Protocol Buffers)

The .pb timing files map every verse in a surah to word-level timestamps.

Protocol Buffer Schema (recitation.proto)

syntax = "proto3";
package recitation;

message WordSegment {
  int32 word_index_0_based = 1;
  int32 word_index_1_based = 2;
  int32 timestamp_from = 3;      // milliseconds from start of surah
  int32 timestamp_to = 4;        // milliseconds from start of surah
}

message VerseSegments {
  repeated WordSegment segments = 1;
}

message SurahTimestamps {
  map<string, VerseSegments> verses = 1;  // key = "surah:ayah" (e.g., "1:1")
}

How It Works

Each .pb file contains a SurahTimestamps message with all verses of that surah. The timestamps are relative to the start of the surah audio file, so you can:

1. Load the surah .opus audio
2. Decode the .pb timing data
3. To play a specific ayah, seek the audio to verses["1:3"].segments[0].timestamp_from milliseconds
4. Highlight words in real-time as currentTimeMs falls between each segment's timestamp_from and timestamp_to
