• Add tests and docs: If you're adding a new integration, please include
  1. a test for the integration, preferably unit tests that do not rely on network access,
  2. an example notebook showing its use. It lives in docs/docs/integrations directory.

tested using below script

pip install --upgrade elevenlabs langchain-community

import getpass
import os
#ELEVEN_API_KEY = 'aaa'

from langchain_community.tools import ElevenLabsText2SpeechTool

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

#tts = ElevenLabsText2SpeechTool(eleven_api_key=ELEVEN_API_KEY)
tts = ElevenLabsText2SpeechTool()
tts.name
print('tts.name',tts.name)


speech_file = tts.run(text_to_speak)
print('speech_file created')

tts.play(speech_file)
print('played speech file')

# Stream the text as speech
tts.stream_speech("This is a... streaming voice!!")

print('streaming test complete')

Ouput after the change

tts.name eleven_labs_text2speech
speech_file created
played speech file
streaming test complete

• Lint and test: Run make format, make lint and make test from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/

Additional guidelines:

• Make sure optional dependencies are imported within a function.
• Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
• Most PRs should not touch more than one package.
• Changes should be backwards compatible.
• If you are adding something to community, do not re-import it in langchain.

Looks like the previous review request comment did not get saved properly. @ccurme , please review.

hey there! This one looks like it might be an interface change on the elevenlabs sdk side, which would be a breaking change in this package for people using this tool with the old sdk

Also, if you're interested in maintaining this integration without us in the loop, we'd love to get an integration package out! Future PRs against langchain would just be {docs updates, as well as registering your package in libs/packages.yml, deprecating this community integration in favor of your integration package}

Here's the guide, and if you have questions, feel free to leave them in the comments on those pages so others can see them! https://python.langchain.com/docs/contributing/how_to/integrations/ <-- this is the right way to handle these kinds of breaking changes moving forward

In the meantime, this change would unfortunately have to be re-implemented in a way that is compatible with both elevenlabs==0.x and elevenlabs==1.x. If you're interested in taking that on, let me know! Otherwise would recommend downgrading to 0.x to get it working
