How do I make text to speech with several voices?
Open Text to speech in the app and switch from Text to Dialogue, or paste a script where each line starts with a name and a colon: the app offers to switch for you. Every name becomes a character with its own voice. Change any of them, then press Voice dialogue. You get one MP3 with all the lines in order.
How much does a dialogue cost?
Exactly what the same text costs in one voice: per 1,000 characters at the rate of the tier (50 credits on Standard, 110 on Enhanced, 160 on Premium), with a minimum of 10 credits. The number of speakers and voices does not change the price, and the total shows on the button before you voice anything.
How long can a dialogue be?
Up to 8 characters and 100 lines, with up to 5,000 characters in a line. A long dialogue is voiced in portions: the first lines, about 5,000 characters, right away, and the rest after you have heard them and decided to go on.
Can the characters speak different languages?
Yes. Each character has a voice of its own, and each voice reads the language of its lines: a teacher in English and a waiter in Spanish, or two native speakers of any of the 31 languages with native voices. All voices in one dialogue come from the same tier.
Can I change one line without redoing the whole dialogue?
Yes. Open the dialogue from your history, edit the lines and voice it again. Unchanged lines keep their audio, and only the changed ones are voiced and charged. Or press Voice this line again on one line: pick another voice, fix a word or add a direction like [whispers], and only that line is voiced anew. The same text costs the line's price again; a changed text costs the price of the new text.
Do voice directions work in a dialogue?
Yes, line by line: type [whispering], [laughs], [pause] or another short direction in English inside the line. Enhanced and Premium voices take any short direction. The universal Standard voices read plain text, so their tags are removed before voicing.
What do I get at the end?
One MP3 of the whole dialogue, with the pause you chose between lines. It stays in your history for 90 days, where you can play it, download it again or edit it.
Can I get subtitles for a dialogue?
Yes, with Enhanced and Premium voices. The arrow next to the MP3 gives you an SRT or VTT file timed word by word to the audio, and Subtitles with names (SRT) puts each character's name in front of their lines, which suits language lessons and translated interviews. Subtitles cost nothing extra; Standard voices do not have them.
Can I use the audio commercially?
Yes. Generation runs on the paid commercial API tiers of our voice providers, whose terms permit commercial use of the generated audio. You are responsible for the content of the script.
