| ❌ Failed - Due to Noise | This outcome will occur if background noise detected | Re-record your paragraphs |
| ❌ Failed - Due to speech recognition | This outcome will occur if significant mismatch detected between the recording and the paragraph text (if accuracy is at least 70% then mismatching words will be underlined) | Re-record your paragraphs |
| ❌ Failed - Due to speaker | A mismatching speaker was detected between the consent and the paragraph | Re-record your paragraphs with the correct speaker |

Perfect voice score
The Voice Score and the number of paragraphs in their various states (i.e not recorded, validated, processing, failed) can be found at the top of the page.
