This notebook shows how to interact with the ElevenLabs API to achieve text-to-speech capabilities. First, you need to set up an ElevenLabs account. You can follow the instructions here. 
%pip install --upgrade --quiet  elevenlabs langchain-community

import os

os.environ["ELEVENLABS_API_KEY"] = ""

​
Usage

from langchain_community.tools import ElevenLabsText2SpeechTool

text_to_speak = "Hello world! I am the real slim shady"

tts = ElevenLabsText2SpeechTool()
tts.name

'eleven_labs_text2speech'
We can generate audio, save it to the temporary file and then play it. 
speech_file = tts.run(text_to_speak)
tts.play(speech_file)
Or stream audio directly. 
tts.stream_speech(text_to_speak)

​
Use within an Agent

from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_openai import OpenAI

llm = OpenAI(temperature=0)
tools = load_tools(["eleven_labs_text2speech"])
agent = initialize_agent(
    tools=tools,
    llm=llm,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)

audio_file = agent.run("Tell me a joke and read it out for me.")
