Voice Cloning
VORA's advanced voice cloning capabilities allow you to create custom voices with just a few audio samples, maintaining the original speaker's characteristics while enabling full emotional expression and multilingual support.
π Enterprise Voice Cloning
Create branded voices for your organization with legal watermarking and content protection features.
Voice cloning with VORA creates high-fidelity digital representations of human voices that can:
Generate new speech content in the original speaker's voice
Maintain emotional expressiveness across different emotions
Support multiple languages while preserving voice characteristics
Scale to any length of content without quality degradation
import sagea
client = sagea.VoraClient( api_key = "your-api-key" )
# Create a custom voice with audio samples
voice_id = client.clone_voice(
name = "my_custom_voice" ,
audio_samples = [
"sample1.wav" ,
"sample2.wav" ,
"sample3.wav"
],
text_transcripts = [
"This is the first training sample." ,
"Here's another sample for the voice model." ,
"And one more sample for better quality."
]
)
# Use the cloned voice
audio = client.synthesize(
text = "Hello! This is my cloned voice speaking." ,
voice_id = voice_id,
model = "vora-v1"
)
For optimal results, provide diverse audio samples:
Minimum Requirements:
3-5 audio samples (30 seconds each minimum)
Clear audio quality (no background noise)
Natural speaking pace and tone
Diverse emotional expressions
Recommended Setup:
10-15 samples for premium quality
Various sentence structures and lengths
Different emotional states (neutral, happy, professional)
Consistent audio format (WAV, 22kHz+)
# Enhanced voice cloning with options
voice_id = client.clone_voice(
name = "professional_narrator" ,
audio_samples = audio_files,
text_transcripts = transcripts,
options = {
"quality" : "premium" , # standard, high, premium
"training_steps" : 2000 ,
"preserve_accent" : True ,
"emotional_range" : "full"
}
)
# Monitor training progress
status = client.get_cloning_status(voice_id)
print ( f "Training progress: { status.progress } %" )
# Test the cloned voice quality
test_audio = client.synthesize(
text = "This is a test of the cloned voice quality." ,
voice_id = voice_id,
model = "vora-v1"
)
# Get similarity score

print ( f "Voice similarity: { similarity.score } %" )
Clone voices that work across multiple languages:
# Clone voice with multilingual support

# Use across different languages
english_audio = client.synthesize(
text = "Hello, welcome to our service." ,
voice_id = multilingual_voice,
language = "en-US"
)
spanish_audio = client.synthesize(
text = "Hola, bienvenido a nuestro servicio." ,
voice_id = multilingual_voice,
language = "es-ES"
)
Maintain emotional expressiveness in cloned voices:
# Test emotional range
emotions = [ "neutral" , "happy" , "professional" , "excited" , "calm" ]
for emotion in emotions:
audio = client.synthesize(
text = f "This is the { emotion } emotion demonstration." ,
voice_id = voice_id,
emotion = emotion,
emotion_intensity = 0.7
)
audio.save( f "test_ { emotion } .wav" )
Fine-tune cloned voices for specific use cases:
# Adapt voice for different contexts
business_voice = client.adapt_voice(
base_voice_id = voice_id,
adaptation_type = "professional" ,
sample_texts = [
"Welcome to our quarterly business review." ,
"The financial projections show positive growth." ,
"Thank you for your attention to this matter."
]
)
# Use adapted voice

emotion = "professional"
)
