PlayHT API SDK

pyht is a Python SDK for the PlayHT's AI Text-to-Speech API. PlayHT builds conversational voice AI models for realtime use cases. With pyht, you can easily convert text into high-quality audio streams in humanlike voice.

Features

Stream text-to-speech in real-time.
Use PlayHT's pre-build voices or create custom voice clones.
Stream text from LLM, and generate audio stream in real-time.
Supports WAV, MP3, PCM, Mulaw, FLAC, and OGG audio formats.
Supports 8KHz, 16KHz, 24KHz, 44.1KHz and 48KHz.

Requirements

Python 3.8+
numpy
simpleaudio

Installation

You can install the pyht SDK using pip:

pip install pyht

Usage

You can use the pyht SDK by creating a Client instance and calling its tts method. Here's a simple example:

from pyht import Client
from dotenv import load_dotenv
from pyht.client import TTSOptions
import os
load_dotenv()

client = Client(
    user_id=os.getenv("PLAY_HT_USER_ID"),
    api_key=os.getenv("PLAY_HT_API_KEY"),
)
options = TTSOptions(voice="s3://voice-cloning-zero-shot/d9ff78ba-d016-47f6-b0ef-dd630f59414e/female-cs/manifest.json")
for chunk in client.tts("Can you tell me your account email or, ah your phone number?", options):
    # do something with the audio chunk
    print(type(chunk))

For a more detailed example with command-line arguments and interactive mode, refer to the provided demo.

Command-Line Demo

You can run the provided demo from the command line.

Note: This demo depends on the following packages:

pip install numpy simpleaudio

python demo/main.py --user YOUR_USER_ID --key YOUR_API_KEY --text "Hello from Play!"

Alternatively, you can run the demo in interactive mode:

python demo/main.py --user YOUR_USER_ID --key YOUR_API_KEY --interactive

In interactive mode, you can input text lines to generate and play audio on-the-fly. An empty line will exit the interactive session.

Get an API Key

To get started with the pyht SDK, you'll need your API Secret Key and User ID. Follow these steps to obtain them:

Access the API Page: Navigate to the API Access page.
Generate Your API Secret Key:
- Click the "Generate Secret Key" button under the "Secret Key" section.
- Your API Secret Key will be displayed. Ensure you copy it and store it securely.
Locate Your User ID: Find and copy your User ID, which can be found on the same page under the "User ID" section.

Keep your API Secret Key confidential. It's crucial not to share it with anyone or include it in publicly accessible code repositories.

llama-cpp-agent

The llama-cpp-agent framework is a tool designed for easy interaction with Large Language Models (LLMs). Allowing users to chat with LLM models, execute structured function calls and get structured output (objects). It provides a simple yet robust interface and supports llama-cpp-python and OpenAI endpoints with GBNF grammar support (like the llama-cpp-python server) and the llama.cpp backend server. It works by generating a formal GGML-BNF grammar of the user defined structures and functions, which is then used by llama.cpp to generate text valid to that grammar. In contrast to most GBNF grammar generators it also supports nested objects, dictionaries, enums and lists of them.
