What does speech data collection in Hyderabad involve?

Dialect profile of Hyderabad

Telangana Telugu alongside Dakhini Urdu, producing a lexical mix found nowhere else.

Cities are not neutral sampling grounds. Urban speech in Hyderabad 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 Telangana as a whole.

Who you can recruit

The only reliable pool for Dakhini Urdu at scale, plus Telangana Telugu.

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

Booth plus field-recording capacity for community-based collection.

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 Telugu 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 Hyderabad, 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.
