• 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
