What does speech data collection in Nagpur involve?

Dialect profile of Nagpur

Varhadi Marathi, materially different from Puneri standard and largely missing from public corpora.

Cities are not neutral sampling grounds. Urban speech in Nagpur carries more code-mixing, more media-influenced pronunciation and a younger age skew than the surrounding districts, so a corpus recorded entirely here will not represent Maharashtra as a whole.

Who you can recruit

The key site for Vidarbha dialect coverage.

Screening verifies the claimed dialect and district rather than accepting self-declaration, because participants routinely under-report regional features when speaking to a recruiter.

Studio and field capability

Partner booth with mobile capture for surrounding districts.

Where the deployment audio is telephony, we capture over a real narrowband path in the same city rather than downsampling studio audio, since the two are not equivalent for model training.

What to record here

• Scripted and spontaneous Marathi speech with urban dialect coverage
• Conversational two-party audio on separate channels
• Telephony and contact-centre style corpora
• Code-mixed English material, which is denser in metro speech
• TTS voice recording where a treated booth is required

When to record elsewhere

If your quota calls for varieties spoken outside Nagpur, the correct answer is field recording in those districts, not a city recording with a dialect label attached. We run mobile kits for exactly this reason, and the cost difference is smaller than the cost of a corpus your evaluation later rejects.
