When try with
typescript 3.6.4

export const SpeechToText = {

const sttCredentials = Object.assign(
{

password: params.speechToTextPassword,

url: params.speechToTextUrl ? params.speechToTextUrl : SpeechToTextV1.URL

);
const sttAuthService = new AuthorizationV1(sttCredentials);
return Observable.create((observer) => {
sttAuthService.getToken(function(err, response) {
if (err) {
console.log('Error retrieving token: ', err);
observer.error('Error retrieving token...');
} else {
const token = response.token || response;
if (params.speechToTextIamApikey) {
observer.next({ accessToken: token, url: sttCredentials.url });
} else {
observer.next({ token: token, url: sttCredentials.url });
}
observer.complete();
}
});
});
}
}
Expect it to return a token.

Authentication changed in v5. See MIGRATION-V5
The SDK service constructors now accept Authenticator objects that are used to authenticate requests. The constructors no longer accept individual credentials like username and password.
Here's an example from the API reference.
const SpeechToTextV1 = require('ibm-watson/speech-to-text/v1');
const { IamAuthenticator } = require('ibm-watson/auth');
const speechToText = new SpeechToTextV1({
authenticator: new IamAuthenticator({
apikey: '{apikey}',
}),
url: '{url}',
});
