Marathi Number Sentences – TTS Dataset
A combined speech dataset of Marathi sentences that contain numbers, amounts, dates and times. It was created to improve how a Marathi TTS model reads numerals in customer-facing contexts (insurance, finance, scheduling), and is used to fine-tune ai4bharat/IndicF5.
Dataset summary
| Split | Utterances | Duration |
|---|---|---|
| v1 – original number sentences | 2,791 | ~3.24 h |
| v2 – extended numbers (amounts, times, dates) | 5,000 | ~5.95 h |
| Combined (this dataset) | 7,791 | ~9.19 h |
- Language: Marathi (
mr) - Script: Devanagari (with some Latin-digit numerals)
- Audio: 24 kHz mono WAV, synthesised with an IndicF5 Marathi fine-tune
- Avg. duration: ~4.2 s per clip

| wavs/num_02791.wav | 73 लाखांच्या कव्हरसाठी वार्षिक प्रीमियम सुमारे ९८,००० रुपये येतो. | 7.17 | v2 |
Generation
Sentences were written by template using number_data/gen_number_sentences.py
(templates in number_sentences.tsv / number_sentences_v2.tsv) and synthesised
with number_data/synth_number_data.py using an IndicF5 Marathi checkpoint.
Themes include:
- insurance premiums and cover amounts (₹ in lakhs / crores)
- callback times and appointment scheduling
- policy term lengths and percentages
- mixed Devanagari and Latin digit formats
Intended use
- Fine-tuning Marathi TTS models for number reading
- Benchmarking Marathi ASR on number-heavy speech
- Research on numeral normalisation in Indic languages
Out of scope: this data is synthetic (generated by a TTS model). It should not be treated as natural human speech.
