Step by Step solution about How to resolve the algorithm Speech synthesis step by step in the JavaScript programming language

1. Speech Synthesis API (JavaScript)

The first code snippet uses the Speech Synthesis API in JavaScript to generate spoken audio from text. It does so by creating a new SpeechSynthesisUtterance object, setting its text content, and then using window.speechSynthesis.speak() to speak the utterance.

2. SAPI (ActiveXObject)

The second code snippet uses the SAPI (Speech Application Programming Interface) in Internet Explorer to generate spoken audio from text. It creates a new ActiveXObject of type "SAPI.SpVoice" and then uses its speak() method to speak the provided text.

Detailed Explanation:

Speech Synthesis API (JavaScript)

• SpeechSynthesisUtterance: Creates a new utterance object that holds the text to be spoken.
• **utterance.text: Sets the text content of the utterance to "This is an example of speech synthesis."
• window.speechSynthesis.speak(utterance): Instructs the browser to speak the utterance using the default voice and settings.

SAPI (ActiveXObject)

• **new ActiveXObject("SAPI.SpVoice"): Creates a new ActiveXObject of type "SAPI.SpVoice", which represents the speech engine.
• **voice.speak("This is an example of speech synthesis."): Instructs the SAPI speech engine to speak the provided text.

Comparison:

• The JavaScript Speech Synthesis API is a modern, cross-platform API that provides a more standardized way to generate spoken audio.
• The SAPI ActiveXObject is an older, platform-specific (Internet Explorer) API that requires the installation of additional components and may not be as reliable on other browsers.
• Both APIs allow developers to control the text to be spoken and provide basic voice and playback options.

var utterance = new SpeechSynthesisUtterance("This is an example of speech synthesis.");
window.speechSynthesis.speak(utterance);


var voice = new ActiveXObject("SAPI.SpVoice");
voice.speak("This is an example of speech synthesis.");
