The post walks through local deployment on macOS using mlx-audio and uv, covering zero-shot generation, voice design with natural language prompts, standard voice cloning, and long-form 'ultimate cloning' with reference audio and transcript. Code examples are provided for each use case, making it a practical guide for self-hosting a capable alternative to ElevenLabs. ## Content Recently, the OpenBMB team released the latest VoxCPM2 model, which has 2B parameters, supports voice cloning, voice design, and high-quality speech synthesis, and supports **30** mainstream languages, including English, Chinese, Japanese, Korean, German, and French. ## VoxCPM2 Features - Supports 30 languages, no language tags required, direct input of text in any supported language. - Supports voice design, input natural language descriptions to generate new voices without reference audio. - Supports voice cloning, with style guidance to control emotion, pace, and expressiveness. - Supports generating high-quality **48kHz** audio. If your work requires the use of ElevenLabs, you can continue reading the content below. By following these steps, you will be able to deploy a completely free TTS service locally. However, if you are looking for open-source alternatives to other popular paid software, you can visit the [BestAlternative](https://www.bestalternative.dev/en) website, which features open-source substitutes for hundreds of popular software. ## VoxCPM Architecture VoxCPM adopts a tokenizer-free, diffusion autoregressive architecture that models speech in continuous latent space rather than discrete tokens.  ## Local Deployment The official VoxCPM2 documentation has detailed how to run VoxCPM2 models using PyTorch and CUDA. Next, I will introduce how to deploy VoxCPM2 models locally on macOS using mlx-audio. **1.Configure the virtual environment** ``` uv venv .venv source .venv/bin/activate ``` **2.Install mlx-audio and soundfile** ``` uv pip install "git+https://github.com/Blaizzy/mlx-audio" --prerelease=allow uv pip install soundfile ``` **3.Download the model.** You can download the corresponding quantization model based on your computer configuration and actual needs.  ``` hf download mlx-community/VoxCPM2-4bit --local-dir ./models/VoxCPM2-4bit # or hf download mlx-community/VoxCPM2-8bit --local-dir ./models/VoxCPM2-8bit # or hf download mlx-community/VoxCPM2-bf16 --local-dir ./models/VoxCPM2-bf16 ```  **4.Zero-shot Generation** ``` import numpy as np from mlx_audio.tts.utils import load from mlx_audio.audio_io import write as audio_write MODEL_DIR = "models/VoxCPM2-8bit" OUTPUT_PATH = "zero_shot.wav" model = load(MODEL_DIR) result = next(model.generate("Hello, this is VoxCPM2 on Apple Silicon.")) audio_mx = result.audio audio_write( str(OUTPUT_PATH), np.array(audio_mx), model.sample_rate, format="wav", ) ``` It should be noted that if the text to be synthesized contains parentheses, it needs to be escaped; otherwise, the speech cannot be synthesized correctly. **5.Voice Design** ``` import numpy as np from mlx_audio.tts.utils import load from mlx_audio.audio_io import write as audio_write MODEL_DIR = "models/VoxCPM2-8bit" OUTPUT_PATH = "voice_design.wav" model = load(MODEL_DIR) result = next(model.generate( text="Hello, welcome to VoxCPM2.", instruct="A young woman, warm and gentle voice", )) audio_mx = result.audio audio_write( str(OUTPUT_PATH), np.array(audio_mx), model.sample_rate, format="wav", ) ``` **6.Voice Cloning** ``` import numpy as np from mlx_audio.tts.utils import load from mlx_audio.audio_io import write as audio_write MODEL_DIR = "models/VoxCPM2-8bit" OUTPUT_PATH = "voice_cloning.wav" model = load(MODEL_DIR) result = next(model.generate( text="Hello, this is VoxCPM2 on Apple Silicon.", ref_audio="lisa.wav", )) audio_mx = result.audio audio_write( str(OUTPUT_PATH), np.array(audio_mx), model.sample_rate, format="wav", ) ``` **7.Ultimate Cloning** For scenarios involving the production of long-form content such as audiobooks, you need to provide both reference audio and the corresponding transcribed text to ensure consistency. ``` import numpy as np from mlx_audio.tts.utils import load from mlx_audio.audio_io import write as audio_write MODEL_DIR = "models/VoxCPM2-8bit" OUTPUT_PATH = "ultimate_cloning.wav" model = load(MODEL_DIR) result = next(model.generate( text="2B-parameter multilingual tokenizer-free TTS model with 48kHz studio-quality output. Supports zero-shot generation, voice design, voice cloning, and continuation for long-form speech. 30 languages including English, Chinese, Indonesian, Japanese, Korean, and more.", prompt_text="VoxCPM2 is a tokenizer-free, diffusion autoregressive Text-to-Speech model", prompt_audio="lisa.wav", )) audio_mx = result.audio audio_write( str(OUTPUT_PATH), np.array(audio_mx), model.sample_rate, format="wav", ) ``` ## Summary [VoxCPM2](https://github.com/OpenBMB/VoxCPM) is a powerful TTS model. If you have speech synthesis needs, you can evaluate its capabilities. If it doesn't meet your needs, you can test Qwen3-TTS, which offers 0.6B and 1.7B sizes and supports 10 mainstream languages ​​including English, Chinese, Japanese, Korean, German, and French. It also supports speech synthesis, voice design, and voice cloning, but you'll need to switch between different models. ## Similar posts on daily.dev - [Pocket TTS: A high quality TTS that gives your CPU a voice](https://daily.dev/posts/pocket-tts-a-high-quality-tts-that-gives-your-cpu-a-voice-vig6uubge) · Hacker News · 2 upvotes · 0 comments - [FluentVox: AI Text-to-Speech for Laravel with Voice Cloning and GPU Acceleration](https://daily.dev/posts/fluentvox-ai-text-to-speech-for-laravel-with-voice-cloning-and-gpu-acceleration-pg7mqtzas) · Laravel News · 4 upvotes · 0 comments --- Tags: [#machine-learning](https://daily.dev/tags/machine-learning), [#python](https://daily.dev/tags/python), [#open-source](https://daily.dev/tags/open-source), [#text-to-speech](https://daily.dev/tags/text-to-speech), [#voice-cloning](https://daily.dev/tags/voice-cloning) [View this post on daily.dev](https://daily.dev/posts/the-free-open-source-alternative-to-elevenlabs-is-finally-here-b28gb2wif) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/the-free-open-source-alternative-to-elevenlabs-is-finally-here-b28gb2wif","headline":"The Free, Open-Source Alternative to ElevenLabs Is Finally Here","text":"VoxCPM2 is a free, open-source TTS model from OpenBMB with 2B parameters supporting 30 languages, voice cloning, voice design, and 48kHz audio output.
