Microsoft speech recognition api

I want to ask a bit about Authentication of this API
Do "The token" of the response have some expired time or something? or is it for eternity?

Documentation link is here : https://www.microsoft.com/cognitive-services/en-us/Speech-api/documentation/API-Reference-REST/BingVoiceRecognition#Authorize

If you want to not have to login each time instead of using the 'Authorization': 'Bearer {TOKEN}' header you could use the 'Ocp-Apim-Subscription-Key': '{YOUR AZURE TOKEN}' in order to not have to make a authorisation factory or more requests than necessary to the application and make it faster

NOTE: {TOKEN} is a JWT token like 

eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzY29wZSI6Imh0dHBzOi8vc3BlZWNoLnBsYXRmb3JtLmJpbmcuY29tIiwic3Vic2NyaXB0aW9uLWlkIjoiZmFhZTNlYTkxNmI1NGMxZWEyODY4MDlhYTg3ZWE1MmUiLCJwcm9kdWN0LWlkIjoiQmluZy5TcGVlY2guUHJldmlldyIsImNvZ25pdGl2ZS1zZXJ2aWNlcy1lbmRwb2ludCI6Imh0dHBzOi8vYXBpLmNvZ25pdGl2ZS5taWNyb3NvZnQuY29tL2ludGVybmFsL3YxLjAvIiwiYXp1cmUtcmVzb3VyY2UtaWQiOiIiLCJpc3MiOiJ1cm46bXMuY29nbml0aXZlc2VydmljZXMiLCJhdWQiOiJ1cm46bXMuc3BlZWNoIiwiZXhwIjoxNTAwODgxNjIzfQ.KdlCrIJ_H0jxs1yyeyYxYR7ucbLuFKT__ep7lGJmGbU

NOTE2: {YOUR AZURE TOKEN} is like d5kals90935b40809dc6k38533c21e85 and you find it here

The request would look like this:

curl -v -X POST "https://speech.platform.bing.com/speech/recognition/interactive/cognitiveservices/v1?language=es-ES&locale=es-ES&format=simple&requestid=req_id" -H "Ocp-Apim-Subscription-Key: d5kals90935b40809dc6k38533c21e85" -H 'Transfer-Encoding: chunked'  -H 'Content-type: audio/wav; codec="audio/pcm"; samplerate=8000' --data-binary @"{BINAYFILE}.wav"

The token is a JSON Web Token (JWT), which—unless it's encrypted—can be decoded to inspect its contents (a web service to perform that task can be found here).

Expiry claims are set with the exp property in the resulting JSON document.
