Handling language scores

Language scores are derived from transcribing free speaking audio and scoring the response in key aspects such as:

• Fluency

• Pronunciation

• Grammar

• Vocabulary

• Coherence

These overall scores help the test creator assess the overall quality of the response in terms of five different rubrics:

• A speechace_score on a scale of 0 to 100

• An ielts_score on a standard IELTS scale of 0 to 9.0

• A pte_score on a standard PTE scale or 10 to 90

• A cefr_score on a standard scale of A0 to C2

• A toeic_score on a standard scale of 0 to 200

The following example snippet from the API results demonstrates the overall scores:
