Short answer

Bengaluru in Karnataka is a recruitment hub for Kannada, Indian English, Hinglish. Urban Kannada under heavy multilingual contact; the strongest Indian English pool in the country. Excellent for Indian English accent bands and technology-domain speakers; native Kannada requires residence screening. Two booths with far-field and device-distance rigs for wake-word capture. It is the right choice when your quota needs the varieties spoken here; it is the wrong choice when you need rural dialects from elsewhere in Karnataka, in which case field recording outside the city is the honest answer.

Dialect profile of Bengaluru

Urban Kannada under heavy multilingual contact; the strongest Indian English pool in the country.

Cities are not neutral sampling grounds. Urban speech in Bengaluru 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 Karnataka as a whole.

Who you can recruit

Excellent for Indian English accent bands and technology-domain speakers; native Kannada requires residence screening.

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

Two booths with far-field and device-distance rigs for wake-word capture.

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 Kannada 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 Bengaluru, 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.
