khaya 0.1.1

Python SDK for the Khaya AI API — translation, ASR, and TTS for African languages

Khaya SDK

Python SDK for the Khaya AI Khaya API — providing translation, automatic speech recognition (ASR), and text-to-speech (TTS) for African languages.

Installation

pip install khaya

Authentication

Get an API key at https://translation.ghananlp.org and set it as an environment variable:

export KHAYA_API_KEY=your_api_key_here

Quick Start

import os
from khaya import KhayaClient

with KhayaClient(os.environ["KHAYA_API_KEY"]) as khaya:
    # Translate text from English to Twi
    result = khaya.translate("Hello, how are you?", "en-tw")
    print(result.json())

    # Transcribe a Twi audio file
    result = khaya.transcribe("path/to/audio.wav", "tw")
    print(result.json())

    # Synthesize speech in Twi
    result = khaya.synthesize("Me ho yɛ", "tw")
    with open("output.mp3", "wb") as f:
        f.write(result.content)

Async Usage

import asyncio
import os
from khaya import KhayaClient

async def main():
    async with KhayaClient(os.environ["KHAYA_API_KEY"]) as khaya:
        result = await khaya.atranslate("Hello", "en-tw")
        print(result.json())

        result = await khaya.atranscribe("path/to/audio.wav", "tw")
        print(result.json())

        result = await khaya.asynthesize("Me ho yɛ", "tw")
        with open("output.mp3", "wb") as f:
            f.write(result.content)

asyncio.run(main())

Error Handling

All errors raise exceptions — never return error dicts. Catch the appropriate exception:

from khaya import KhayaClient
from khaya.exceptions import (
    AuthenticationError,
    RateLimitError,
    TranslationError,
    APIError,
)

khaya = KhayaClient(api_key="your-key")

try:
    result = khaya.translate("Hello", "en-tw")
    print(result.json())
except AuthenticationError:
    print("Invalid API key. Check your KHAYA_API_KEY.")
except RateLimitError as e:
    print(f"Rate limit hit: {e.message}")
except TranslationError as e:
    print(f"Translation failed ({e.status_code}): {e.message}")
except APIError as e:
    print(f"API error ({e.status_code}): {e.message}")

Configuration

from khaya import KhayaClient
from khaya.config import Settings

config = Settings(
    api_key="your-key",
    timeout=60,          # seconds (default: 30)
    retry_attempts=5,    # retries on transient failures (default: 3)
)
khaya = KhayaClient(api_key="your-key", config=config)
