Frequently Asked Questions

Most speech recognition providers focus on transcribing what the user is speaking. Speechace is designed and trained to assess how well the user is speaking. Our focus is on evaluating the spoken language of a non-native speaker – i.e. how intelligible, natural and rich is their language. Our models are trained and optimized for this specific purpose.

If your platform and developers are ready, and you follow the docs and samples, you can implement one speaking activity in less than 1 week and trial it with users. Our API trial is designed to allow you to test out the API before you have to pay for a subscription.

We go to great lengths in running independent, blind, randomized evaluations for all our models to ensure our API results are within close agreement range with qualified human evaluators. Our API has been independently verified by both Academic and Corporate entities.

Please fill out the Contact Us form below and we’d be glad to share technical reports detailing our performance and accuracy metrics.

Speechace tackles the challenge of accent through ensuring the training and validation datasets represent a wide range of speakers in terms of demographics, language proficiency and accent. This allows our general model to be optimized for the target result of measuring intelligible, natural, and fluent speech irrespective of accent.

The mere presence of accent is not considered a criteria for penalizing a speaker, so long as it does not interfere with intelligibility and fluency.
