Text to Speech Generation
Convert Text into Speech
The text-to-speech feature enables you to convert written text into spoken audio with a selection of voices and languages. You can seamlessly integrate this audio into a clip by specifying the desired voice and the text to be spoken.
{
"asset": {
"type": "text-to-speech",
"text": "Good evening, in Sydney tonight we’re tracking a developing story as unexpected storms roll in across the city, bringing with them flash flooding warnings and major disruptions to the evening commute.",
"voice": "Amy"
},
"start": 0,
"length": "auto"
}
This request will embed the generated speech at the beginning of your video, with the duration automatically matching the length of the generated audio. For more details on optimizing timing, refer to smart clips.
Translating text
To create an audio file in a different language, use the language option. Ensure that you select a voice compatible with the desired language.
{
"asset": {
"type": "text-to-speech",
"text": "Good evening, in Sydney tonight we’re tracking a developing story as unexpected storms roll in across the city, bringing with them flash flooding warnings and major disruptions to the evening commute.",
"voice": "Seoyeon",
"language": "ko-KR"
},
"start": 0,
"length": "auto"
}
