Where the two meet

Wake-word false accepts and rejects spike on Indian phonetics That is a asr model training problem, and it is solved by data shaped like this:

  • Hundreds to thousands of hours of verbatim-transcribed speech
  • Wide speaker diversity: age, gender, region, education, recording condition
  • Speaker-disjoint train/dev/test splits

Your evaluation criteria

  • Can recordings be captured at the distances and conditions the device sees?
  • Are entity-heavy prompt sets available (names, addresses, PIN codes, amounts)?
  • Can negative wake-word data be collected alongside positives?

Metrics

  • Word error rate overall and per dialect
  • Entity error rate on names and numbers
  • Code-switch token accuracy
04

Pitfalls

  • Read-speech-only corpora that do not transfer to spontaneous audio
  • Speaker leakage across splits inflating reported accuracy
  • Normalised-only transcripts with the raw text discarded
05

Contract points

  • Device-specific recording conditions
  • Exclusive use of the collected wake-word data
  • Staged delivery per firmware milestone

Frequently asked

What does a first engagement look like?

Usually a scoped pilot: one language, an evaluation set plus a first training batch, delivered in three to five weeks, followed by the full programme.

Can you match our existing vendor's schema?

Yes. Working to your schema avoids a conversion pass and keeps deliveries comparable across vendors.

How is provenance documented?

Per-item contributor records and consent mapped to IDs in the manifest.
