Error while deploying firebase cloud function - node.js

Question

I am trying to deploy my functions but that shows an error. I am trying to use cloud speech api & cloud translation api with firebase cloud function.
const functions = require('firebase-functions');
const Speech = require('#google-cloud/speech');
const Translate = require('#google-cloud/translate');
const speech = Speech({keyFilename: "credentials.json"});
const translate = Translate({keyFilename: "credentials.json"});
const Encoding = Speech.v1.types.RecognitionConfig.AudioEncoding;
function getLanguageWithoutLocale(languageCode) {
if (languageCode.indexOf("-") >= 0) {
return languageCode.substring(0, languageCode.indexOf("-"));
}
return languageCode;
}
exports.onUpload = functions.database
.ref("/uploads/{uploadId}")
.onWrite((event) => {
let data = event.data.val();
let language = data.language ? data.language : "en";
let sampleRate = data.sampleRate ? data.sampleRate : 16000;
let encoding = data.encoding === "FLAC" ? Encoding.FLAC : Encoding.AMR;
let request = {
config: {
languageCode : language,
sampleRateHertz : sampleRate,
encoding : encoding
},
audio: { uri : `gs://mimming-babelfire.appspot.com/${data.fullPath}` }
};
return speech.recognize(request).then((response) => {
let transcript = response[0].results[0].alternatives[0].transcript;
return event.data.adminRef.root
.child("transcripts").child(event.params.uploadId)
.set({text: transcript, language: language});
});
});
exports.onTranscript = functions.database
.ref("/transcripts/{transcriptId}")
.onWrite((event) => {
let value = event.data.val();
let transcriptId = event.params.transcriptId;
let text = value.text ? value.text : value;
let languages = ["en", "es", "pt", "de", "ja", "hi", "nl", "fr", "pl"];
// All supported languages: https://cloud.google.com/translate/docs/languages
let from = value.language ? getLanguageWithoutLocale(value.language) : "en";
let promises = languages.map(to => {
console.log(`translating from '${from}' to '${to}', text '${text}'`);
// Call the Google Cloud Platform Translate API
if (from === to) {
return event.data.adminRef.root
.child("translations").child(transcriptId).child(to)
.set({text: text, language: from});
} else {
return translate.translate(text, {
from: from,
to: to
}).then(result => {
// Write the translation to the database
let translation = result[0];
return event.data.adminRef.root
.child("translations").child(transcriptId).child(to)
.set({text: translation, language: to});
});
}
});
return Promise.all(promises);
});
I installed #google-cloud/speech and #google-cloud/translate in npm.
it shows error

please help me to find the error if anyone knows. Thank you in advance

It's complaining about this line:
const speech = Speech({keyFilename: "credentials.json"});
You're using Speech as if it's a function, but it's not a function.
Looking at the documentation, it seems that you're supposed to initialize it like this:
const speech = require('#google-cloud/speech');
const client = new speech.SpeechClient();
