Introduction to Conversational Actions
Conversational actions are a powerful tool that allows you to create a rich and interactive experience for your app or service using Google Assistant. The goal of a conversational action is to provide users with a seamless and natural conversation that feels like interacting with a real person. In this article, we will explore the various features and functionality of SSML (Speech Synthesis Markup Language), and how you can leverage them to enhance your conversational apps with Assistant.
What is SSML?
SSML stands for Speech Synthesis Markup Language. It is an industry-standard markup language governed by the World Wide Web Consortium (W3C). SSML allows developers to specify the pronunciation and other speech-related features when using Assistant's text-to-speech capabilities. If you are familiar with XML or HTML, SSML will look familiar to you, as it shares similar syntax and structure.
Basic Functionality of SSML
At its core, SSML allows you to supply text to a text-to-speech generator, which then produces a sound file that speaks the contents of your text. This basic functionality enables you to create natural pauses, emphasize certain words or phrases, and control the overall flow and intonation of the speech output.
SSML Features for Text-to-Speech Conversion
SSML offers a wide range of features that can add depth and character to the speech voiced by the Assistant. Let's explore some of the key features you can utilize to enhance your conversational actions:
Pausing and Emphasis
SSML allows you to control the timing and emphasis of speech by incorporating pauses and emphasizing specific words or phrases. This feature enables you to create a more natural and expressive conversation with the Assistant.
Phoneme Tag for Customized Pronunciation
The phoneme tag in SSML allows you to customize the pronunciation of specific words. This is particularly useful when you want the Assistant to pronounce a word in a specific way or when dealing with regional variations in pronunciation.
Duration Tag for Time Interpretation
The duration tag is used to indicate that a specific portion of text should be interpreted as a duration of time. By using the say-as tag with the interpret-as parameter set to duration, you can specify how the time measurement should be read by the speech engine.
Voice Tag for Multiple Voices
With the recent addition of the voice tag, Assistant's SSML engine now supports generating audio in multiple voices and languages within a single SSML file. This feature allows you to create more engaging and dynamic conversations by representing different characters or personas.
Lang Tag for Different Languages
The lang tag in SSML enables you to use the same voice in a different language for a subset of your text. This is useful when you want to incorporate foreign language phrases or when you need to represent different languages within the same conversational action.
Implementation Examples
To better understand how these SSML features can be utilized, let's explore some implementation examples. We will demonstrate how to use the phoneme tag to customize pronunciation, the duration tag for time interpretation, and the voice and lang tags for multiple voices and languages.
Additional Resources
For more detailed information and examples on how to implement SSML features in your conversational actions, refer to the official documentation provided by Google Assistant. The documentation covers in-depth explanations and usage guidelines for each SSML feature, ensuring you have all the necessary resources to create exceptional conversational experiences.
Conclusion
In this article, we have explored the various features and functionality of SSML for creating conversational actions with Google Assistant. By leveraging the capabilities of SSML, developers can enhance their apps and services by creating more engaging, natural, and interactive conversations. The SSML features discussed here provide developers with powerful tools to customize speech, control timing and emphasis, and incorporate multiple languages and voices. Incorporating these features will help you deliver a seamless and immersive conversational experience for users interacting with your app or service through Google Assistant.
