google翻译的强大,就像我们公司的slogan : "让语言无国界,让世人心相通"
友情提示: google相关的服务都是需要翻墙的,不然在大陆无法访问
写这篇文章的目的就是为了整合一下这方面的资料, 大概是因为被墙,网上关于这方面的资料很少,有些是过于老旧,甚至是不适用的,所以就不得不做个笔记就当作是探探路。
google语音识别
- 到
google注册相关的API_KEY, 地址:https://cloud.google.com/speech-to-text/docs/samples - 下载demo
https://github.com/GoogleCloudPlatform/ios-docs-samples/tree/master/speech/Objective-C/Speech-REST-Nonstreaming - 录制语音文件存于沙盒, 上传语音文件到
https://speech.googleapis.com/v1/speech:recognize?key=xxxxx
核心代码:
NSString *service = @"https://speech.googleapis.com/v1/speech:recognize";
service = [service stringByAppendingString:@"?key="];
service = [service stringByAppendingString:API_KEY];
NSData *audioData = [NSData dataWithContentsOfFile:[self soundFilePath]];//沙盒里的录音文件 具体看google提供的demo
NSDictionary *configRequest = @{@"encoding":@"LINEAR16",
@"sampleRateHertz":@(SAMPLE_RATE),
@"languageCode":@"zh-cn",
@"maxAlternatives":@30};
NSDictionary *audioRequest = @{@"content":[audioData base64EncodedStringWithOptions:0]};
NSDictionary *requestDictionary = @{@"config":configRequest,
@"audio":audioRequest};
NSError *error;
NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestDictionary
options:0
error:&error];
NSString *path = service;
NSURL *URL = [NSURL URLWithString:path];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
// if your API key has a bundle ID restriction, specify the bundle ID like this:
[request addValue:[[NSBundle mainBundle] bundleIdentifier] forHTTPHeaderField:@"X-Ios-Bundle-Identifier"];
NSString *contentType = @"application/json";
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:requestData];
[request setHTTPMethod:@"POST"];
NSURLSessionTask *task =
[[NSURLSession sharedSession]
dataTaskWithRequest:request
completionHandler:
^(NSData *data, NSURLResponse *response, NSError *error) {
dispatch_async(dispatch_get_main_queue(),
^{
NSString *stringResult = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
_textView.text = stringResult;
NSLog(@"RESULT: %@ ", stringResult);
});
}];
[task resume];
google 文本翻译
文本翻译和语音识别类似,都需要API_KEY,同样是POST请求
/**
MARK:- 文本互转
@param text 文本
@param targetCode 翻译的对应语言代码
@param callBack 回调结果json字符串
*/
- (void)translateOriginText:(NSString *)text
targetCode:(NSString *)targetCode
callBack:(void(^)(NSString *objStr))callBack{
NSString *urlStr = [NSString stringWithFormat:@"https://translation.googleapis.com/language/translate/v2?key=%@",API_KEY];
NSURL *URL = [NSURL URLWithString: urlStr];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request addValue:[[NSBundle mainBundle] bundleIdentifier] forHTTPHeaderField:@"X-Ios-Bundle-Identifier"];
NSString *contentType = @"application/json";
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
// q: 原文本 tagret: 目标语言的代码 zh-cn,en-us...等
NSDictionary *requestDictionary = @{ @"q" : text, @"target" : targetCode };
NSError *error;
NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestDictionary options:0 error:&error];
[request setHTTPBody:requestData];
[request setHTTPMethod:@"POST"];
NSURLSessionTask *task =
[[NSURLSession sharedSession]
dataTaskWithRequest:request
completionHandler:
^(NSData *data, NSURLResponse *response, NSError *error) {
dispatch_async(dispatch_get_main_queue(),
^{
NSString *stringResult = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"RESULT: %@ ", stringResult);
!callBack? : callBack(stringResult);
});
}];
[task resume];
}
google 语音合成
- 合成是免费的 , 然后是这个接口
http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&ttsspeed=1 - 参数组成
//基地址
BASE_URL = @"http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&ttsspeed=1"
//拼接规则和get请求类似
total //标准为100个字符为一组 然后total是总共多少组
idx //下标,第几组
textlen //所有文字的计数,就是这个字符串的长度
q //合成的文字内容,中文的话需要转编码utf-8最为合适
tl //语言，跟识别的语言一致
主要参数介绍:ie: 输入参数编码 input-encode 一般为utf-8oe: 输入参数编码 output-encode 一般为utf-8ttsspeed: 合成的语速tl: 目标语言代码 target languagehl: 当地语言代码 home language
url编码前:http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&ttsspeed=1&total=1&idx=1&textlen=6&q=某某某是傻逼&tl=zh-cn
url编码后:http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&ttsspeed=1&total=1&idx=1&textlen=6&q=%E9%99%88%E8%89%AF%E8%89%AF%E6%98%AF%E5%82%BB%E9%80%BC&tl=zh-cn
核心代码
///MARK:- 文本 转 语音在线合成
- (void)synthesisAudioWithTranslateWithText:(NSString *)text{
NSString *baseUrl = @"http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&ttsspeed=1";
//url编码
NSCharacterSet *encodeUrlSet = [NSCharacterSet URLQueryAllowedCharacterSet];
NSString *encodeContent = [text stringByAddingPercentEncodingWithAllowedCharacters:encodeUrlSet];
NSString *urlStr = [NSString stringWithFormat:@"%@&total=1&idx=1&textlen=%ld&q=%@&tl=%@",baseUrl,text.length,encodeContent,self.targetCode];
NSURL *url = [NSURL URLWithString: urlStr];
//播放拼接的链接
UIWebView *web = [[UIWebView alloc] init];
web.hidden = YES;
[self.view addSubview: web];
NSURLRequest *req = [[NSURLRequest alloc] initWithURL:url];
[web loadRequest: req];
}
