iFLYTEK released Spark-ASR-2.0 on September 23, 2026, with a goal beyond transcribing speech accurately: producing text that reads more like finished prose. Launch reports describe improvements over Spark-ASR-1.0, but the performance figures and comparisons come from the company rather than an independently reproducible evaluation. 5

How does Spark-ASR-2.0 compare with 1.0?
Recognition accuracy: iFLYTEK reports lower word error rates, particularly for Chinese–English mixed speech, dialects and noisy audio. It also reports improvements for specialist terminology, low-volume or fast speech, and children’s voices. The available launch reporting does not establish a reliable overall percentage-point accuracy gain. 5
6
Text fluency: The new model is intended to use context to trim redundant wording and make transcripts more coherent and readable. That is a different goal from a strictly verbatim transcript, and users who need an exact record should check how the output handles spoken wording. 5
7
Inference cost: iFLYTEK says overall inference cost is about 10% higher than for Spark-ASR-1.0. That is a claim about the cost of running the model, not a published 10% increase in API pricing. 5
6
What techniques are behind the reported gains?
The launch reporting identifies three approaches: cooperation between non-autoregressive recognition and LLM-enhanced autoregressive processing; joint augmentation of Chinese–English text and audio; and dynamic injection of context. iFLYTEK associates the combined approach with better handling of code-switching, dialects, technical terms, difficult acoustics and transcript formatting. The reporting does not isolate how much each technique contributes to any one improvement. 5

In particular, the cited difficult-acoustic cases are high noise and low-volume speech, along with fast speech and children’s voices. “Low-volume” should not be mistaken for a claim that the model can transcribe silent audio. 5
6
How many Chinese dialects does it support?
There is no well-established Spark-ASR-2.0 dialect count in the available evidence. One report says it covers 38 dialect and minority-language variants, while another describes recognition of dialects from 202 cities. Separately, iFLYTEK documentation advertises 202 dialects for a real-time transcription service without establishing that the figure applies to Spark-ASR-2.0. These descriptions should not be combined into a verified specification for the model. 3

17
Likewise, assertions that Spark-ASR-2.0 surpasses the industry’s best systems on dialects, noise or low-volume speech are reported company comparisons, not independently established rankings. 5
6
Rollout, API access and what comes next
A gradual rollout in iFLYTEK Input Method was scheduled to begin September 24, 2026. Reports also describe API access and a trial entry point through the iFLYTEK Open Platform, with later integrations planned for AI glasses, smart office notebooks and iFLYTEK Tingjian transcription products. Those product plans do not confirm that every integration is already live. 6

For subsequent development, iFLYTEK has identified three experience targets: rejecting speech from irrelevant speakers, editing recognized text through voice commands, and presenting results with attention to emotion. The cited reporting does not provide a verified release date for those capabilities. 18
