Description

The neoTalk plugin for VisualNEO Web enables text-to-speech, speech recognition, and audio recording capabilities, allowing applications to interact with users through voice and audio functionalities. This plugin is ideal for applications needing accessible communication, voice-guided interactions, or multimedia content creation. Here’s a comprehensive overview of its key features and usage:

Text-to-Speech (TTS)

The neoTalkSpeak command synthesizes speech from the provided text, allowing customization of the voice, rate, and pitch.

• Command: neoTalkSpeak
• Syntax: neoTalkSpeak "text" "voice" rate pitch
• text: The text to be spoken.
• voice: Name of the voice (leave empty for default).
• rate: Speech rate (0.1 to 10, default 1).
• pitch: Speech pitch (0 to 2, default 1).

Example:

neoTalkSpeak "Hello, welcome to our app!" "" 1 1

This uses the default voice to say the text at a standard rate and pitch.

Pausing, Resuming, and Cancelling Speech

• neoTalkPause: Pauses the ongoing speech.
• Syntax: neoTalkPause
• neoTalkResume: Resumes paused speech.
• Syntax: neoTalkResume
• neoTalkCancel: Cancels all current speech synthesis.
• Syntax: neoTalkCancel

These commands give users control over the text-to-speech playback, allowing for interactive voice guidance.

Retrieving Available Voices

The neoTalkGetVoices command retrieves a list of available voices for text-to-speech, storing them in an array variable.

• Command: neoTalkGetVoices
• Syntax: neoTalkGetVoices returnVar
• returnVar: Array variable to store voice names.

Example:

neoTalkGetVoices "[voiceArray]"

This populates voiceArray with available voice options for use in neoTalkSpeak.

Speech Recognition

The neoTalkStartRecognition command begins speech recognition, converting spoken words into text and storing them in a specified variable.

• Command: neoTalkStartRecognition
• Syntax: neoTalkStartRecognition returnVar continuous lang callBack
• returnVar: Variable to store recognized text.
• continuous: Set to true for continuous recognition (false stops on silence).
• lang: Language code (e.g., "en-US" for English).
• callBack: Optional callback subroutine triggered after recognition.

Example:

neoTalkStartRecognition "[recognizedText]" true "en-US" "onRecognitionComplete"

This starts speech recognition in English, storing the results in recognizedText.

• neoTalkStopRecognition: Stops active speech recognition.
• Syntax: neoTalkStopRecognition

Audio Recording and Playback

The plugin supports recording and playback of audio directly from the user’s microphone.

• Commands:
