🛠️ Usage

Basic Example

from Simpler_Kokoro import SimplerKokoro

# Create an instance
sk = SimplerKokoro()

# Load the available voices
voices = sk.list_voices()

# (optional) Print out the voices
for voice in voices:
    print(voice) # Print out the voice object

# Use the first voice as example
selected_voice = voices[0]

# Generate speech
sk.generate(
    text='Hello, this is a test of the Simpler Kokoro voice synthesis.', # Text to generate 
    voice=selected_voice.name, # Grab the name from the selected voice
    output_path='output.wav' # Select the output path.
)

Generate Speech with Subtitles

from Simpler_Kokoro import SimplerKokoro

# Create an instance
sk = SimplerKokoro()

# Load the available voices
voices = sk.list_voices()

# Use the first voice as example
selected_voice = voices[0]

# Generate speech
sk.generate(
    text='Hello, this will generate a subtitles.srt file along with output.wav', # Text to generate
    voice=selected_voice.name, # Grab the name from the selected voice
    output_path='output.wav', # Select the output path
    write_subtitles=True, # Enable subtitle generation
    subtitles_path='subtitles.srt', # (optional) Specify the subtitle .srt filename
    subtitles_word_level=True # (optional) Enable word level timestamps
)

Generate Speech with Custom Speed

from Simpler_Kokoro import SimplerKokoro

# Create an instance
sk = SimplerKokoro()

# Load the available voices
voices = sk.list_voices()

# Use the first voice as example
selected_voice = voices[0]

# Generate speech
sk.generate(
    text='Hello, this is a test of the Simpler Kokoro voice synthesis.', # Text to generate 
    voice=selected_voice.name, # Grab the name from the selected voice
    output_path='output.wav', # Select the output path
    speed=1.5 # This represents 150% Speed. 1 means 100% and 0.5 means 50%
)

Specify a Path to Download Models

from Simpler_Kokoro import SimplerKokoro

# Create an instance
sk = SimplerKokoro(models_dir='<PATH TO PUT MODELS>') # Put in the path where you want the models to be saved here

# Load the available voices
voices = sk.list_voices()

# Use the first voice as example
selected_voice = voices[0]

# Generate speech
sk.generate(
    text='Select a custom directory for the models!', # Text to generate 
    voice=selected_voice.name, # Grab the name from the selected voice
    output_path='output.wav' # Select the output path.
)
