Mix Language
This feature can help you to synthesize your text in more than one language during the same conversion.
For example - you can synthesize Spanish and English text in the same conversion.
<lang xml:lang="en-IN">Hello world ! How are you?</lang><lang xml:lang="es-ES"> Hola Mundo ! ¿Cómo estás?</lang>
Please note - Make sure that your Text content written outside the SSML tag should be in the same language as selected in language dropdown.
For example-
Hello, How are you? <lang xml:lang="es-ES">Hola Mundo ! ¿Cómo estás?</lang>
In this example the content written outside the tag (Hello, How are you?) is in English. So, default language selection should be English.

Convert Text into IPA Phoneme format
This SSML tag allows you to control pronunciation by specifying phonetic representations of words. This can be particularly useful when words are pronounced differently than they are spelled.
How to use-
- Choose your TTS language on the above widget, add your word & click Convert. It will transcribe it in IPA format. You may separate words or phrases with commas. For example: Jeanne, Person.
- Now copy the converted IPA formatted word and use it within the SSML tag as highlighted below.
- Finally, you may use the SSML tag within your content.
