How do I use Bing translation service to play audio for specific words on android? -
i trying port wp7 app android. using bing translation service download & play audio specific words/phrases. how can in android? in bing, stream comes .wav file. here wp7 code:
private void button1_click(object sender, routedeventargs e) { this.speak(); } public void speak() { string appid = "your id"; string text = "speak me"; string language = "en"; string uri = "http://api.microsofttranslator.com/v2/http.svc/speak?appid=" + appid + "&text=" + text + "&language=" + language + "&file=speak.wav"; webclient client = new webclient(); client.openreadcompleted += new openreadcompletedeventhandler(client_openreadcompleted); client.openreadasync(new uri(uri)); } void client_openreadcompleted(object sender, openreadcompletedeventargs e) { if (e.error != null) return; var sound = e.result; player.source = null; string filename = "myaudio"; using (isolatedstoragefile userstoreforapplication = isolatedstoragefile.getuserstoreforapplication()) { bool fileexists = userstoreforapplication.fileexists(filename); if (fileexists) { userstoreforapplication.deletefile(filename); } var isolatedstoragefilestream = userstoreforapplication.createfile(filename); using (isolatedstoragefilestream) { savefile(e.result, isolatedstoragefilestream); if (e.error == null) { player.setsource(isolatedstoragefilestream); } } } } public static void savefile(system.io.stream input, system.io.stream output) { try { byte[] buffer = new byte[32768]; while (true) { int read = input.read(buffer, 0, buffer.length); if (read <= 0) { return; } output.write(buffer, 0, read); } } catch (exception ex) { messagebox.show(ex.tostring()); } } void mysound_mediafailed(object sender, exceptionroutedeventargs e) { messagebox.show(e.errorexception.message); } void mysound_mediaopened(object sender, routedeventargs e) { player.play(); }
i thought i'd drop generic response executing http requests , downloading files, more troublesome thing ran how microsoft azure wants authentication. evidently using app id deprecated , api extremely picky request headers , parameters.
in case, i'd suggest starting writing asynctask handles executing httpurlconnection. ended with:
/** * tailor-made http request microsoft azure, downloading file * specified location. */ private class httpdownloadfile extends asynctask<string, integer, string> { private string mdir; @override protected string doinbackground(string... params) { if (params.length < 2) { throw new illegalargumentexception( "two arguments required " + getclass().getsimplename()); } string response = null; string uri = params[0]; string query = params[1]; try { if (query.length() > 0) { uri += "?" + query; } url url = new url(uri); httpurlconnection connection = (httpurlconnection) url .openconnection(); connection.setrequestproperty("content-type", "application/x-www-form-urlencoded"); if (params.length > 2) { connection.setrequestproperty("authorization", "bearer " + params[2]); } connection.connect(); int filelength = connection.getcontentlength(); string charset = preferred_charset; if (connection.getcontentencoding() != null) { charset = connection.getcontentencoding(); } inputstream input; outputstream output; boolean iserror = false; try { input = connection.getinputstream(); output = new fileoutputstream(mdir); } catch (ioexception e) { input = connection.geterrorstream(); output = new bytearrayoutputstream(); iserror = true; } byte data[] = new byte[1024]; long total = 0; int count; while ((count = input.read(data)) != -1) { total += count; publishprogress((int) (total * 100 / filelength)); output.write(data, 0, count); } output.flush(); if (!iserror) { response = mdir; } else { response = ((bytearrayoutputstream) output).tostring(charset); log.e(tag, response); response = null; } output.close(); input.close(); } catch (exception e) { log.e(tag, "failed requesting " + uri, e); } return response; } } you can execute task correct parameters:
httpdownloadfile task = new httpdownloadfile(); task.execute( getstring(r.string.url_speak), getstring(r.string.url_speak_query, text, tolanguage, file), accesstoken, environment.getexternalstoragedirectory().getpath() + "/temp.wav"); my strings.xml contains:
<string name="url_speak" formatted="false" translate="false">http://api.microsofttranslator.com/v2/http.svc/speak</string> <string name="url_speak_query" formatted="false" translate="false">text=%s&language=%s&file=%s</string> unfortunately, implies have code obtaining authentication token done. no worries! i've written complete code of that, too:
