Parameters
Not collected
Architecture
Autoregressive language model with flow-matching acoustic generation and a causal vocoderSource for Architecture (opens in a new tab)

The report explicitly identifies its evaluated system with the hosted 3.0 Plus model. No parameter count is stated here, and the mapping is not extended to Flash or 3.1.

Languages
System voices: Chinese and English, varying by voice. Cloned voices: 16 languages plus Chinese regional varietiesSource for Languages (opens in a new tab)
Maximum prompt characters
20,000Source for Maximum prompt characters (opens in a new tab)

Per call/segment in the SpeechSynthesizer SDK. Bidirectional synthesis permits 200,000 cumulative characters; not a token context window.

Streaming text limits
20,000 characters per segment; 200,000 cumulativeSource for Streaming text limits (opens in a new tab)
Audio formats
PCM, WAV, MP3, OpusSource for Audio formats (opens in a new tab)
Audio sample rates
8000, 16000, 22050, 24000, 44100, 48000Source for Audio sample rates (opens in a new tab)

Output sample rates in Hz; default 22,050 Hz. These are audio sampling rates, not billable token rates.

Voice controls
Volume 0–100; rate and pitch 0.5–2.0; MP3/Opus bitrate 6–510 kbpsSource for Voice controls (opens in a new tab)
Request mode
WebSocket synthesis; complete-input or bidirectional text streamingSource for Request mode (opens in a new tab)
Voice cloning
SupportedSource for Voice cloning (opens in a new tab)

Custom voice enrollment is a separate workflow; its pricing is not included in synthesis rates.

Stock voice catalog
System voices and a separate base/cloned voice catalogSource for Stock voice catalog (opens in a new tab)
Audio direction
Natural-language delivery instructions; fine-grained emotion tags in one-way streamingSource for Audio direction (opens in a new tab)

The guide restricts inline tags to the 3.0 Plus/Flash models and one-way streaming.

Voice design
SupportedSource for Voice design (opens in a new tab)

The dedicated voice-design API lists this target model in Beijing. Earlier generic overview copy disagrees; this does not imply Singapore support.

Usage metering
Input characters; synthesized output has no separate chargeSource for Usage metering (opens in a new tab)
Research speech tokenizer rate
12.5 HzSource for Research speech tokenizer rate (opens in a new tab)

Research speech-tokenizer rate, not a published billing conversion from audio seconds to API tokens.

Data retention
Standard API inference prompts and responses are retained up to 30 days, subject to legal/security exceptions; stateful files remain until deleted. This release is absent from the listed ZDR-supported audio families.Source for Data retention (opens in a new tab)

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Inference from the release-specific hosted Model Studio identity, official technical/deployment documentation and reviewed Qwen/FunAudioLLM public-weight inventories. No matching weights are published in those inventories. Public Qwen-Audio, Qwen3-TTS, Qwen3-ASR, CosyVoice and Fun-ASR checkpoints have distinct names; no equivalence with this hosted selector is assumed. This is not a claim that the whole family or all Alibaba models are closed-weight.
