# Pronunciation Assessment (streaming version) API documentation

# Interface description

The ability interface for automatic evaluation of pronunciation level, pronunciation errors, defect localization and problem analysis through intelligent speech technology. The core technologies involved can be mainly divided into two parts: automatic evaluation technology of Chinese Mandarin pronunciation level and automatic evaluation technology of English pronunciation level.

1. Get the authentication code: apply for appid from IFLYTEK open platform and add (streaming interface) to get the interface key APIKey and APISecret
   
2. Integration of Websocket interface: generic interface + parameter description, Chinese and English test question format will be different, see test question format description test question format description
   

# Interface Demo

Example demo Please click here to download.
Currently, we only provide demos for some development languages, please refer to the following interface documentation for other languages.

# Interface requirements

# Interface call flow

1. Parameter uploading phase, as detailed in the description of business parameters (business):
   Parameter first upload, data.status=0,and set cmd="ssb";
   
2. Audio upload phase, during which audio data uploading begins:
   The first frame of audio needs to be set with cmd="auw", aus=1, data.status=1;
   Intermediate frame audio needs to be set with cmd="auw", aus=2, data.status=1;
   The last frame of audio needs to be set with cmd="auw", aus=4, and data.status=2;

# Interface authentication

In the handshake phase, the requestor needs to sign the request, and the server verifies the legitimacy of the request through the signature.

# Authentication Methods

By adding authentication related parameters after the request address. Example url:

ws://ise-api-sg.xf-yun.com/v2/ise?authorization=
YXBpX2tleT0ia2V5eHh4eHh4eHg4ZWUyNzkzNDg1MTlleHh4eHh4eHgiLCBhbGdvc

tSM0trQ0hPcz0i &host=ise-api.xfyun.cn&date=Tue%2C+22+Dec+2020+06%3A29%3A31+GMT

Authentication Parameters:

# authorization parameter detailed generation rules

(1) Get the interface keys APIKey and APISecret.
In the console page, you can check it after registration.
(2) The format of the parameter authorization base64 encoding before (authorization_origin) is as follows.

api_key="$api_key",algorithm="hmac-sha256",headers="host date request-line",signature="$signature"

where api_key is the APIKey obtained on the console, algorithm is the encryption algorithm (only hmac-sha256 is supported), and headers are the parameters involved in signing (see comments below).
signature is a string that is signed using a cryptographic algorithm and encoded with base64 for the parameters involved in the signature, see below.

Note: headers are the parameters involved in signing; note that it is the fixed parameter names ("host date request-line"), not the values of these parameters.

(3) The rules for the original field (signature_origin) of the signature are as follows.

The signature raw field consists of the host, date, and request-line parameters stitched together in the format
The format of the splice is (\n is a line break, ':' followed by a space):

host: $host\ndate: $date\n$request-line

suppose that...

request url = ws://ise-api-sg.xf-yun.com
date = Wed, 10 Jul 2019 07:35:43 GMT

Then the signature original field (signature_origin) is:

host: ise-api-sg.xf-yun.com
date: Wed, 10 Jul 2019 07:35:43 GMT
GET /v2/open-ise HTTP/1.1

signature_sha=hmac-sha256(signature_origin,$apiSecret)

signature=base64(signature_sha)

Assumptions

APISecret = secretxxxxxxxxxx2df7900c09xxxxxxxxxxx
date = Wed, 10 Jul 2019 07:35:43 GMT

signature=WC1tTz2DI+A8nKPNhz7t7lIhG1VBKDhD3K+R3KkCHOs=

api_key="keyxxxxxxxxxx8ee279348519exxxxxxxxxx", algorithm="hmac-sha256",
headers="host date request-line", signature="WC1tTz2DI+
A8nKPNhz7t7lIhG1VBKDhD3K+R3KkCHOs="

(7) Finally, the authorization_origin is base64 encoded to get the final authorization parameter.

authorization = base64(authorization_origin)
Example:
authorization=

# authentication url example (Java)

public static String getAuthUrl(String hostUrl, String apiKey, String apiSecret) throws Exception {
  URL url = new URL(hostUrl);
  SimpleDateFormat format = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z", Locale.US);
  format.setTimeZone(TimeZone.getTimeZone("GMT"));
  String date = format.format(new Date());
  //String date = format.format(new Date());
  //System.err.println(date);
  StringBuilder builder = new StringBuilder("host: ").append(url.getHost()).append("\n").//
    append("date: ").append(date).append("\n").//
    append("GET ").append(url.getPath()).append(" HTTP/1.1");
  //System.err.println(builder);
  Charset charset = Charset.forName("UTF-8");
  Mac mac = Mac.getInstance("hmacsha256");
  SecretKeySpec spec = new SecretKeySpec(apiSecret.getBytes(charset), "hmacsha256");
  mac.init(spec);
  byte[] hexDigits = mac.doFinal(builder.toString().getBytes(charset));
  String sha = Base64.getEncoder().encodeToString(hexDigits);
  //System.err.println(sha);
  String authorization = String.format("api_key=\"%s\", algorithm=\"%s\", headers=\"%s\", signature=\"%s\"", apiKey, "hmac-sha256", "host date request-line", sha);
  //System.err.println(authorization);
  HttpUrl httpUrl = HttpUrl.parse("https://" + url.getHost() + url.getPath()).newBuilder().//
    addQueryParameter("authorization", Base64.getEncoder().encodeToString(authorization.getBytes(charset))).//
    addQueryParameter("date", date).//
    addQueryParameter("host", url.getHost()).//
    build();
  return httpUrl.toString();
 }

# Authentication results

If the handshake is successful, HTTP 101 status code will be returned, indicating that the protocol upgrade is successful; if the handshake fails, different HTTP Code status codes will be returned according to different error types, and at the same time carry the error description information, the detailed error descriptions are as follows:

Handshake failure return example:

    HTTP/1.1 401 Forbidden
    Date: Thu, 06 Dec 2018 07:55:16 GMT
    Content-Length: 116
    Content-Type: text/plain； charset=utf-8
    {
        "message": "HMAC signature does not match"
    }

# Interface data transmission and reception

After a successful handshake the client and server will establish a websocket connection, the client can upload and receive data at the same time through the websocket connection.

//Connection successful, start sending data
int frameSize = 1280; // the size of each audio frame, it is recommended to send 1280B every 40ms, the size can be adjusted, but do not exceed 19200B, that is, after the base64 compression can not be more than 26000B, otherwise, it will be reported as an error 10163 data length error.
int intervel = 40;
int status = 0; // status of the audio
try (FileInputStream fs = new FileInputStream(file)) {
 byte[] buffer = new byte[frameSize];
 //Send Audio

1. The websocket-version supported by the server is 13, please make sure the framework used by the client supports this version.
   
2. All frames returned by the server are of type TextMessage, which corresponds to opcode=1 in the protocol frame of native Websocket, please make sure that the frame type parsed by the client must be of this type, if not, please try to upgrade the version of the client framework, or change the technical framework.
   
3. If there is a frame-splitting problem, that is, a json packet is returned to the client in multiple frames, resulting in failure of the client to parse the json. Most of the time, this problem is caused by the client's framework to Websocket protocol parsing problems, if it occurs, please try to upgrade the framework version, or replace the technical framework.
   
4. client session ends if you need to close the connection, try to ensure that the Websocket error code passed to the server side is 1000 (if the client-side framework does not provide an interface to pass the error code when closing. )(If the client-side framework does not provide an interface to pass the error code when closing, then there is no need to focus on this article).
   
5. Please note that the number of bytes in a frame size is different for different audio formats, we suggest: uncompressed PCM format, 40ms interval between each audio transmission, 1280B bytes per audio transmission; the size can be adjusted, but the maximum should not exceed 19200B, i.e., after base64 compression, it should not be more than 26000B, or else it will be reported as Error 10163 Data Too Long Error.

How do I approach this topic?

[macanswer]
You have to narrow down your topic. For example, you may talk about what college students can do to protect our environment. After that, you need to do some research to collect relevant information as much as possible. Then, you should organize your arguments well. Logical organization is very important.

1. The Goose Thief

1.1.  Tom went to primary school in the countryside. Near his classroom, there was a small pond where two geese were raised. Students were all fond of them. One day, when Tom passed the school kitchen, he heard the cooks talking about killing the geese for the teachers' Christmas dinner. Tom got angry, and said to himself, "I won't let them be eaten!" That night, Tom worked out a plan. He was going to hide them somewhere far away from the school. The next morning, Tom went to school in his father's big coat. During the break, he rushed to the pond. Without anyone around, he caught the geese and pushed them inside the coat. However, the geese were larger than he had thought, and they tried very hard to free themselves from the coat. The big noise caught the notice of the head teacher and the students, and they all ran to the pond. The head teacher asked for an explanation. Looking at the teacher with fear, Tom told the story and said, "It is unfair to them. We all love them!" The head teacher smiled and promised not to have them killed for the Christmas dinner.
