## Response

### 200

Geslaagde response

- `characters` (list of ForcedAlignmentCharacterResponseModel, required) — Lijst met tekens en hun tijdsinformatie.
- `words` (list of ForcedAlignmentWordResponseModel, required) — Lijst met woorden en hun timinginformatie.

- `start` (double, required) — De starttijd van het teken in seconden.
- `end` (double, required) — De eindtijd van het teken in seconden.

### ForcedAlignmentWordResponseModel

Model dat één woord met de timinginformatie van de aligner vertegenwoordigt.

- `text` (string, required) — Het woord dat is getranscribeerd.
- `start` (double, required) — De starttijd van het woord in seconden.
- `end` (double, required) — De eindtijd van het woord in seconden.
- `loss` (double, required) — De gemiddelde alignment loss/confidencescore voor dit woord, berekend op basis van de tekens waaruit het bestaat.

### ValidationError
