tool = load_tool('TextToSpeech', device='cuda')

# apply tool
audio = tool('Hello, this is a text to audio demo.')
print(audio)

With Lagent

from lagent import ReAct, GPTAPI, ActionExecutor
from agentlego.apis import load_tool

# load tools and build agent
# please set `OPENAI_API_KEY` in your environment variable.
tool = load_tool('TextToSpeech', device='cuda').to_lagent()
agent = ReAct(GPTAPI(temperature=0.), action_executor=ActionExecutor([tool]))

# agent running with the tool.
ret = agent.chat(f'Please introduce the highest mountain and speak out.')
for step in ret.inner_steps[1:]:
    print('------')
    print(step['content'])
