Working with AI voices

Voice Instructions

Voice Instructions let you add Identity, Affect, Tone, Emotion and Pronunciation to your voice.

Example:

Press the "Random ✨" button for inspiration

Press "Help" to see some examples

Add pauses

Same as on our regular voices you can now add pauses with the tag <break time="1s"/>
Example: Mary had a little lamb <break time="2s"/> Whose fleece was white as snow.
Pauses can be between 1-60 seconds long. Please enter whole numbers only (e.g. 1, 2, 3). Decimal numbers like 1.5 are not allowed.

How do I select a language?

AI voices detect the language automatically. However, AI voices do not support ALL languages. Here is the list of languages that are supported:
Afrikaans, Arabic, Armenian, Azerbaijani, Belarusian, Bosnian, Bulgarian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Kannada, Kazakh, Korean, Latvian, Lithuanian, Macedonian, Malay, Maori, Marathi, Nepali, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Tagalog, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese, Welsh.

How do I change the tone or pitch of the output voice?

Switch on Add Instructions and describe how the text should sound, for example "whisper", "speak slowly and calmly", "sound excited" or "use a strong British accent". The new voices follow these instructions especially well. Without instructions, the AI chooses the tone from the context of the text, including punctuation like exclamation points or dashes.

Disclaimer about AI voices

The TTS voices you are hearing are AI-generated and not human voices. Although this may be self-explanatory, it is mandatory for us to clarify this here.

Facts about the Portuguese language:

The Portuguese language is spoken by more than 220 million people and its one of the best Romance language globally. The Portuguese language is spoken mostly in Brazil and Portugal, but it's also a common language in Guinea-Bissau, Cape Verde, Macau, East Timor, Equatorial Guinea and Mozambique. There are other small groups of Portuguese speakers found in Malacca Malaysia, Goa, Diu in India and Daman.

The Portuguese Language History

The Portuguese language is a Latin descendant, and it was brought to Iberian Peninsula in 218BC by Roman soldiers, merchants, and settlers. In the 9th century AD, the first sigh of Portuguese word was recorded in a romance letter. And in 1920 king Denis decreed a change of Portuguese language that was known as the "Vulgar Language" to Portuguese language and pronounced it as an official language. Other languages that have influenced the Portuguese language include French, and this is due to the extensive infiltration of the French customs and manners in Portugal during the eleventh centuries. During that period the Frenchmen traveled to Portugal as scholars, state men, and courtiers.

The Reformed Language

The reformed Portuguese language was adopted in 1916, and the words spelled according to their pronunciation. And in Brazil, a slightly modified form was approved in 1943 and later revised to a more natural version in 1970 and 2009 a new orthography to unite the written Portuguese was adopted.

The Portuguese vowels have a French pronunciation making it easy for those who know Spanish, French and Italian learn the language faster, and the alphabets do not have the K, W, and Y.
