Alibaba Cloud Model Studio:Qwen-Audio-ASR-Filetrans non-real-time speech recognition Android SDK

url

String

Yes

Service endpoints:

• wss://dashscope.aliyuncs.com/api/v1/services/audio/asr/transcription

• China (Beijing): wss://{WorkspaceId}.cn-beijing.maas.aliyuncs.com/api/v1/services/audio/asr/transcription

• Singapore: wss://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1/services/audio/asr/transcription

Replace {WorkspaceId} with your actual Workspace ID.

apikey

String

Yes

The API key.

service_mode

String

Yes

The run mode. Fixed to "1" for recorded speech recognition.

device_id

String

Yes

A unique string that identifies the end user. Set it to an in-app user ID or a device identifier generated by the client. This ID is mainly used for log tracing and troubleshooting.

debug_path

String

No

The storage path for the log file.

This parameter takes effect only when save_log is set to true in the initialize interface. In that case, you must set the log file path, or an error is reported.

At most two log files are kept locally.

max_log_file_size

int

No

The maximum size of the log file, in bytes.

This parameter takes effect only when save_log is set to true in the initialize interface.

Default: 104857600 (100 * 1024 * 1024 bytes, that is, 100 MiB).

log_track_level

int

No

The filter level for the log content sent through the log callback (onFileTransLogTrackCallback).

Default: 2.

Valid values:

• 0: LOG_LEVEL_VERBOSE

• 1: LOG_LEVEL_DEBUG

• 2: LOG_LEVEL_INFO

• 3: LOG_LEVEL_WARNING

• 4: LOG_LEVEL_ERROR

• 5: LOG_LEVEL_NONE (turns off this feature)

Note: log_track_level and level (set through the initialize interface) together determine which logs are ultimately sent to the callback. A log is sent to the callback only when its level value is greater than or equal to both log_track_level and level. For example, if log_track_level is set to 2 (INFO) and level is set to 3 (WARNING), only logs at WARNING level or higher (value >= 3) are sent to the callback.

file_urls

array[string]

Yes

A list of URLs of the audio or video files to transcribe. HTTP and HTTPS are supported. A single request supports only one URL. For input requirements such as supported audio formats, file size limits, and duration limits, see Audio specifications.

If the recording is stored in Alibaba Cloud OSS, the RESTful API supports temporary URLs prefixed with oss://, whereas the SDK does not support oss://-prefixed temporary URLs.

async_request

boolean

No

Whether the recognition request is asynchronous.

Default: false.

Valid values:

• true: asynchronous request
• false: synchronous request

apikey

string

No

If the apikey in Connection and control parameters is a temporary API key, you can update it here to avoid expiration.

nls_config

object

Yes

The core configuration object for speech recognition. It contains key parameters such as model selection and recognition control.

nls_config.model

string

Yes

The model name.

nls_config.special_word_filter

object

No

The sensitive words to process during speech recognition. You can set a different handling method for each sensitive word. For details, see Sensitive word filtering.

nls_config.channel_id

array[integer]

No

The index of the audio tracks to recognize in a multi-track audio file. The index starts at 0. For example, [0] recognizes the first track, and [0, 1] recognizes the first and second tracks at the same time. If you omit this parameter, only the first track is processed.

Default value: [0].

nls_config.diarization_enabled

boolean

No

Whether to enable speaker diarization. Disabled by default.

Applies only to mono audio. Multi-channel audio does not support speaker diarization.

When enabled, the recognition result includes a speaker_id field that distinguishes different speakers.

Default: false.

For an example of speaker_id, see Recognition result description.

nls_config.speaker_count

integer

No

A reference value for the number of speakers. The valid range is an integer from 2 to 100 (inclusive).

By default, the number of speakers is detected automatically. If you set this value, it only guides the algorithm to output the specified count when possible and does not guarantee that exact count.

No default value.

nls_config.vocabulary_id

string

No

The ID of a precompiled hot word list.

Generate this ID in advance by calling the create hot word list API. Pass the ID during recognition to use the hot words in the list.

Suitable for scenarios where the vocabulary is known and relatively stable, and where you need to reuse the same word list across requests.

For usage details, see Precompiled hotwords.

nls_config.input_context

array

No

A list of messages containing optional conversation context to improve recognition accuracy.

[
  {
    "role": "user",
    "content": [
      {
        "type": "input_text",
        "text": "你好啊，我是通义千问，有什么可以帮助你的？"
      }
    ]
  }
]

nls_config.instant_vocabulary

object

No

Instant hotwords, passed as key-value pairs. Each key is the hotword text (string), and each value is its weight (integer). No precompiled hotword list is required. Use this parameter for temporary, session-level hotwords.

Valid weights are integers from 1 to 5, or 50. A higher weight from 1 to 5 makes the model more likely to output the hotword. A weight of 50 defines a super hotword and significantly improves recall. You can specify up to 50 super hotwords.

If you also configure precompiled hotwords, the two sets are merged. If the merged set exceeds 2000 hotwords, 2000 are selected at random. For usage, see Instant hotwords.

{
  "张三": 5,
  "李四": 5
}

nls_config.language_hints

array[string]

No

The language codes to recognize. If you can't determine the language in advance, leave it unset and the model detects the language automatically.

You can set up to 4 values. If you set more, only the first 4 take effect.

callback

INativeFileTransCallback

The implementation of the event and data callback interface.

parameters

String

A JSON string that contains the authentication, connection, and debugging parameters. See Connection and control parameters.

level

Constants.LogLevel

Controls the print level of the SDK's own logs.

save_log

boolean

Whether to save logs locally. If true, specify the path with debug_path in Connection and control parameters, and optionally set the file size with max_log_file_size.

params

String

The nls_config parameter in Speech recognition parameters. Parameters other than nls_config cannot be set through this method.

Example:

{
    "nls_config": {
        "model":"qwen-audio-3.0-asr-flash-filetrans",
        "diarization_enabled": false
    }
}

        "model":"qwen-audio-3.0-asr-flash-filetrans",
        "diarization_enabled": false
    }
}

task_id
