| | # Marathi Sentence-Level ASR Dataset |
| |
|
| | ## 📌 Overview |
| |
|
| | This dataset contains sentence-level Marathi speech segments aligned with transcripts. |
| |
|
| | The dataset was created by extracting subtitle timestamps (SRV3 format) from Marathi YouTube content and segmenting the corresponding audio using precise time alignment. |
| |
|
| | Each sample contains: |
| |
|
| | - A WAV audio file (sentence-level) |
| | - The corresponding Marathi transcript text |
| |
|
| | This dataset is suitable for: |
| |
|
| | - Whisper fine-tuning |
| | - Wav2Vec2 CTC training |
| | - Marathi speech recognition research |
| | - ASR benchmarking |
| |
