How to use Petra voice in your videos

To use Petra voice in your videos, you can use the following JSON2Video code:

{
    "type": "voice",
    "model": "azure",
    "voice": "sl-SI-PetraNeural",
    "text": "Spomladi vrt oživi s pisanimi cvetlicami in petjem ptic. Stara hrastova drevesa ponuja senco obiskovalcem, medtem ko metulji plešejo med rozami. Majhen vodnjak ustvarja mirne zvoke, kar naredi to popolno mesto za sprostitev in uživanje v lepoti narave."
}

$scene->addElement([
	'type' => 'voice',
	'model' => 'azure',
	'voice' => 'sl-SI-PetraNeural',
	'text' => 'Spomladi vrt oživi s pisanimi cvetlicami in petjem ptic. Stara hrastova drevesa ponuja senco obiskovalcem, medtem ko metulji plešejo med rozami. Majhen vodnjak ustvarja mirne zvoke, kar naredi to popolno mesto za sprostitev in uživanje v lepoti narave.'
]);

scene.addElement({
	"type": "voice",
	"model": "azure",
	"voice": "sl-SI-PetraNeural",
	"text": "Spomladi vrt oživi s pisanimi cvetlicami in petjem ptic. Stara hrastova drevesa ponuja senco obiskovalcem, medtem ko metulji plešejo med rozami. Majhen vodnjak ustvarja mirne zvoke, kar naredi to popolno mesto za sprostitev in uživanje v lepoti narave."
});

Petra supports SSML

SSML stands for Speech Synthesis Markup Language. It's a way to add instructions to your text so that a Text-To-Speech (TTS) system knows how to read it aloud.

You use SSML like HTML, but for controlling speech. It helps you adjust things like: Pronunciation, Pauses, Pitch and Volume, Emphasis, Speaking Rate.

{
    "type": "voice",
    "voice": "sl-SI-PetraNeural",
    "text": "<speak>Hello, <break time="500ms"/> how are you today? <emphasis level="strong">This is important!</emphasis></speak>"
}

$scene->addElement([
	'type' => 'voice',
	'voice' => 'sl-SI-PetraNeural',
	'text' => '<speak>Hello, <break time="500ms"/> how are you today? <emphasis level="strong">This is important!</emphasis></speak>'
]);

scene.addElement({
	"type": "voice",
	"voice": "sl-SI-PetraNeural",
	"text": "<speak>Hello, <break time="500ms"/> how are you today? <emphasis level="strong">This is important!</emphasis></speak>"
});

Petra is a neural voice

In Azure Cognitive Services, a Neural voice refers to a voice generated using neural network technology. This means the Text-To-Speech system uses advanced machine learning models to create more natural, human-like speech compared to traditional methods.

Key characteristics of Neural voices:

• More expressive and realistic
• Better at handling pitch, tone, and rhythm variations
• Sounds closer to how humans naturally speak
