SI vocabulary generation starts with collecting reference utterances from

≥400 speakers with:

• An equal mixture of males and females

• Accents from all regions of the country of intended use

• ~15% non-native speakers.

The samples should be generated from a randomly-ordered list, with each word spoken twice

and with a dummy word at the beginning and end. There must be >2 sec between each sample

for accurate data processing. To provide the audio fidelity required for high-quality recognition

training, a DAT recorder, together with the microphone that will be used in the final application,

is required. To ensure data integrity, data is submitted to Oki after collecting samples from the

first 20 speakers for initial screening. If acceptable, then the remaining collection may proceed.

If substitution errors are possible, collection of spare words during initial collection is

recommended. For example, alternate words to “Stop” and “Top” could be “Halt” and “First.”

Collections should contain a wide variety of the background sound conditions that will exist

during actual usage. For example, if the collection is for use in an automobile, conditions such

as vehicle speed, road conditions, various window opening positions, heater or AC blower

speeds and radio volumes should be varied during the collection. The signal-to-noise ratio

should be maintained at

≥ 20dB.
