VoxCPM2 vs OmniVoice vs Qwen3-TTS: Which Voice Model to Use (2026)

VoxCPM2, OmniVoice and Qwen3-TTS are the three strongest voice models in Voice Creator Pro, and each one has a different strength. This comparison covers sample rate, languages, cloning, emotion and hardware, with the same scripts run through all three.

Quick picks

• VoxCPM2: highest sample rate, with 48kHz output straight from the model
• OmniVoice: best for multilingual work, with 600+ languages and accents that hold
• Qwen3-TTS: best emotion control, with 13 emotions at 5 intensities

VoxCPM2 vs OmniVoice vs Qwen3-TTS at a Glance

	VoxCPM2	OmniVoice	Qwen3-TTS
Standout	48kHz output	600+ languages	Emotion control
Languages	30 + 9 Chinese dialects	600+	10
Voice design	Free-form, layered	Structured attributes	Free-form
Emotion	Inferred from text	From the reference clip	13 emotions, 5 intensities
Speed	Slowest	Fastest	Middle
Best for	Narration, trailers	Localization, accents	Audiobooks, acting

All three clone zero-shot from a short reference clip, run in both the desktop app and VCP Cloud, and get the same text normalization in Voice Creator Pro. The differences are in sound, reach and control.

Audio Quality: VoxCPM2 Outputs 48kHz Directly

VoxCPM2 is the only one of the three that outputs 48kHz audio straight from the model, with no upsampler in between. OmniVoice and Qwen3-TTS output 24kHz.

Languages: OmniVoice Covers 600+, VoxCPM2 30, Qwen3-TTS 10

OmniVoice speaks over 600 languages, far more than the other two combined. It also keeps a speaker's accent when the voice switches language, so an Italian speaker cloned into English still sounds Italian.

VoxCPM2 covers 30 languages plus nine Chinese dialects, which is enough for most international creators. Qwen3-TTS covers 10. If your language is outside those lists, OmniVoice is the only choice of the three.

Voice Cloning: All Three Are Zero-Shot

All three models clone a voice from a 3 to 10 second reference clip, with no training step. A longer reference does not make a better clone, so a clean 7 second clip is a good default.

In our earlier Qwen3-TTS vs OmniVoice vs Chatterbox cloning test, Qwen3-TTS scored the highest speaker similarity (0.913 against OmniVoice's 0.887), though the gap was hard to hear. VoxCPM2 wasn't part of that test; the samples below put it next to the other two on the same reference.

Emotion Control: Qwen3-TTS Is the Only One You Can Direct

Qwen3-TTS is the only one of the three with an emotion control. In Voice Creator Pro you assign one of 13 emotions to a line and pick one of 5 intensities, and it works on cloned voices too. This is a Voice Creator Pro layer; the base Qwen3-TTS model doesn't expose it.

The other two take emotion from what you give them:

• VoxCPM2 infers emotion from the words it speaks. An angry line reads angrier than a neutral one, so the script does much of the acting.
• OmniVoice carries emotion from the reference clip. Clone someone speaking through tears and the clone sounds shaky too. It also takes 13 non-verbal tags such as [laughter] and [sigh], which add non-verbal sounds to a line.

If emotion is the main thing you need, our guide to adding emotion to text to speech covers every method across the models.

Voice Design: Three Different Ways to Build a Voice

All three models can design a new voice with no recording, but each takes a different kind of input:

• VoxCPM2 reads a free-form description written in layers: who is speaking, what the voice is made of, and how and where it performs. Naming a setting ("perfect for an epic movie trailer") steers the whole read.
• Qwen3-TTS also takes a free-form description, in a similar style. The practical difference from VoxCPM2 is language reach.
• OmniVoice uses structured attributes such as age, gender, pitch and accent instead of a description. Its headline strength is ten English accents that it renders reliably.

Here is the same brief run through all three, with no reference recording. VoxCPM2 and Qwen3-TTS got one written description of a calm, low-pitched documentary narrator; OmniVoice got its closest attributes (male, middle-aged, low pitch). Each model builds its own voice, so the three sound like different people.

Pick OmniVoice when you need a specific English accent. Pick VoxCPM2 or Qwen3-TTS when you can describe the character in words. Each has a full guide: the VoxCPM2 voice design guide, the OmniVoice voice design guide and the Qwen3-TTS prompting guide. The AI voice design guide compares the approaches side by side.

Speed and Hardware: OmniVoice Is Fastest, VoxCPM2 Slowest

OmniVoice generates fastest of the three. We cloned the same voice reading the same line (about 7 seconds of speech) in the desktop app on an 8 GB RTX 3070 laptop GPU. Each model ran the line twice in a row, and we timed the second run, so loading the model isn't counted:

• OmniVoice: 12 seconds
• Qwen3-TTS: 19 seconds
• VoxCPM2: 38 seconds

That makes OmniVoice about 1.6 times faster than Qwen3-TTS and about 3 times faster than VoxCPM2 on this card. The gap adds up on long narration.

All three fit on an 8 GB graphics card. The desktop app's own estimates of video memory (VRAM) are:

• VoxCPM2: about 5.5 GB
• Qwen3-TTS: about 3.9 GB for the Higher Quality model, 1.7 GB for the Faster one
• OmniVoice: about 2 GB

In VCP Cloud, none of this matters: all three run on our servers from any browser, with no GPU and nothing to install.

Numbers and Prices: A Tie Inside Voice Creator Pro

Inside Voice Creator Pro, all three read numbers, dates, prices and acronyms correctly, because the app normalizes text before it reaches any model. The base open-source OmniVoice stumbles on prices like $1,249.99 when you run it yourself; in Voice Creator Pro it doesn't. So for scripts full of figures, pick on the other categories.

Which Model Should You Use?

Pick by what your project needs most:

• Pick VoxCPM2 if you want 48kHz output: documentary narration, trailers, audiobooks that will be heard on good headphones, or anything mixed under music.
• Pick OmniVoice if you work across languages or accents: localization, dubbing a voice into many markets, a specific English accent, or high-volume generation where speed matters.
• Pick Qwen3-TTS if you need to direct the performance: audiobooks with emotional scenes, character reads, or a cloned voice that has to sound angry, tender or afraid on cue.

Many projects use more than one. A common pattern is designing a narrator in VoxCPM2 for the main read and switching to Qwen3-TTS for lines that need a specific emotion.

Run VoxCPM2, OmniVoice and Qwen3-TTS in One App

Voice Creator Pro runs all three models in one interface, so you can clone or design a voice once and switch models to compare. Each also has its own page with samples: VoxCPM2, OmniVoice and Qwen3-TTS.

The desktop app runs every model locally and offline on Windows and Mac, as a one-time purchase with unlimited generations. VCP Cloud runs the same models in your browser, with a free tier to start.
