Frequently asked questions
What languages are supported for transcription?
Parakeel models support 50+ languages including English, Portuguese, Spanish, French, German, Mandarin, Japanese, and many more. Specify the language for best results.
Can I clone a specific voice?
Yes! Use the clone_voice tool with a reference audio sample (a few seconds is enough) and the text you want the cloned voice to speak.
What is speaker diarization?
Speaker diarization identifies 'who spoke when' in an audio recording. It segments the audio by speaker and returns timestamps for each speaker's turns.
What audio formats are supported?
The API supports WAV, MP3, FLAC, OGG, and most common audio formats. For best transcription accuracy, use high-quality WAV or FLAC files at 16kHz or higher sample rate.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
