Language & Speech Processing

Libraries for natural language processing, speech synthesis, and language detection.

  • Speech Provider Python 2025

    Python package for accessing text-to-speech APIs in a uniform way.

    Example usage:
    # Import the package
from speech_provider import get_voice_provider

# Basic usage
provider = get_voice_provider()

# Get available voices for a specific language
voices = provider.get_voices(lang='en-US')

if voices:
    # Create and play an utterance with the first available voice
    utterance = voices[0].create_utterance('Hello, welcome to my application!')

    # Start speaking
    utterance.play()

# Use with Eleven Labs for higher quality voices
elevenlabs_provider = get_voice_provider(
    elevenlab_api_key='your-api-key',
    cache_max_age=3600  # Cache for 1 hour
)

# Get default voice for a language
default_voice = elevenlabs_provider.get_default_voice(lang='zh-CN')

if default_voice:
    utterance = default_voice.create_utterance('你好，欢迎使用我的应用程序！')
    utterance.play()

# Get voices for specific language
voices = provider.get_voices(lang='fr-FR')
for voice in voices:
    print(f"Voice: {voice.name}, Language: {voice.lang}")

  • Contextual Language Detection Python 2025

    A context-aware language detection library that improves accuracy by considering document-level language patterns.

    Example usage:
    # Basic usage with context-awareness
from contextual_langdetect import contextual_detect

# Example multilingual text
sentences = [
    "你好。",                           # Chinese
    "你好吗?",                          # Chinese
    "很好。",                           # Could be detected as Japanese without context
    "我家也有四个,刚好。",                # Chinese
    "那么现在天气很冷,你要开暖气吗?",      # Chinese (Wu dialect)
    "Okay, fine I'll see you next week.", # English
    "Great, I'll see you then."          # English
]

# Context-aware detection (default)
languages = contextual_detect(sentences)
print(languages)  # ['zh', 'zh', 'zh', 'zh', 'zh', 'en', 'en']

# Context-unaware detection
languages = contextual_detect(sentences, context_correction=False)
print(languages)  # ['zh', 'zh', 'ja', 'zh', 'wuu', 'en', 'en']

# Get language distribution in a document
from contextual_langdetect.detection import count_by_language

mixed_sentences = [
    "Hello world.",        # English
    "Bonjour le monde.",   # French
    "Hallo Welt.",         # German
    "Hello again."         # English
]

counts = count_by_language(mixed_sentences)
print(counts)  # {'en': 2, 'fr': 1, 'de': 1}

# Get the majority language in a document
from contextual_langdetect.detection import get_majority_language

majority = get_majority_language(mixed_sentences)
print(majority)  # 'en'

}

function draw() {
  // Start drawing to a layer
  beginLayer();
  background(100);
  fill('blue');
  circle(width / 2, height / 2, 100);
  endLayer();

  // Create a named layer
  beginLayer('overlay');
  noFill();
  stroke('red');
  strokeWeight(3);
  rect(width / 4, height / 4, width / 2, height / 2);
  endLayer();

  rectMode(CENTER);
}

function draw() {
  background(220);

  // Rotate around a specific point (100, 200)
  // instead of around the canvas origin
  push();
  const angle = radians(frameCount);
  rotateAbout(angle, 100, 200);
  rect(100, 200, 50, 50);
  pop();

  // Scale around a specific point (300, 200)
  push();
  const scale = 1 + 0.5 * sin(frameCount / 30);
  scaleAbout(scale, 300, 200);
