Question

美好的一天！

在开发我的Android应用程序时需要帮助。可以将扬声器标签的默认名称更改为自定义名称，例如人名。我想像我这样创建这样的对话。

 Jhon: Hi
 Marie: Hello
 Jhon: Good Day To you marie..
 Marie:......

如果可以更改扬声器标签的默认名称，请帮助我，我需要您的帮助我这样创造的

private RecognizeOptions getRecognizeOptions(InputStream captureStream) {
    return new RecognizeOptions.Builder()
            .audio(captureStream)
            .contentType(ContentType.OPUS.toString())
            .model("en-US_BroadbandModel")
            .interimResults(true)
            .inactivityTimeout(2000)
            .timestamps(true)
            .speakerLabels(true)
            .maxAlternatives(3)
            .smartFormatting(true)
            .timestamps(true)
            .wordConfidence(true)
            .build();
}

这是.speakerLabels的方法

        endTime = Double.valueOf(speakerLabel.getTo());
        speaker = speakerLabel.getSpeaker();
    }

    }

}


private static CountDownLatch lock = new CountDownLatch(1);

}

其中的输出是这样的

 speaker 0: Hi
 speaker 1: Hello
 speaker 0: Good Day To you marie..
 speaker 1:......

我想这样输出

 Jhon: Hi
 Marie: Hello
 Jhon: Good Day To you marie..
 Marie:......

我的问题是。是否有可能像在ibm watspon中对文本api的讲话中那样创建，因为我在他们的文档中阅读过，他们没有提及如何更改标签，我只是想澄清一下

Answer 1

API或文档中都没有任何内容暗示可以使用服务本身来修改输出中的标签。 https://cloud.ibm.com/docs/services/speech-to-text/output.html#speaker_labels

如何将ibm watson语音中的扬声器标签更改为android中的text api？
