Pemahaman audio

Gemini dapat menganalisis input audio dan menghasilkan respons teks.

Python

from google import genai
import base64

client = genai.Client()

uploaded_file = client.files.upload(file="path/to/sample.mp3")

interaction = client.interactions.create(
    model="gemini-3.5-flash",
    input=[
        {"type": "text", "text": "Describe this audio clip"},
        {
            "type": "audio",
            "uri": uploaded_file.uri,
            "mime_type": uploaded_file.mime_type
        }
    ]
)
print(interaction.output_text)

JavaScript

import { GoogleGenAI } from "@google/genai";

const client = new GoogleGenAI({});

const uploadedFile = await client.files.upload({
    file: "path/to/sample.mp3",
    config: { mime_type: "audio/mp3" }
});

const interaction = await client.interactions.create({
    model: "gemini-3.5-flash",
    input: [
        {type: "text", text: "Describe this audio clip"},
        {
            type: "audio",
            uri: uploadedFile.uri,
            mime_type: uploadedFile.mimeType
        }
    ]
});
console.log(interaction.output_text);

Ringkasan

Gemini dapat menganalisis dan memahami input audio serta menghasilkan respons teks, sehingga memungkinkan kasus penggunaan seperti:

  • Mendeskripsikan, meringkas, atau menjawab pertanyaan tentang konten audio
  • Transkripsi dan terjemahan (speech to text)
  • Diarisasi pembicara (mengidentifikasi pembicara yang berbeda)
  • Deteksi emosi dalam ucapan dan musik
  • Menganalisis segmen tertentu dengan stempel waktu

Untuk interaksi suara dan video real-time, lihat Live API. Untuk model speech to text khusus dengan dukungan transkripsi real-time, gunakan Google Cloud Speech-to-Text API.

Mentranskripsikan speech to text

Contoh ini menunjukkan cara mentranskripsikan, menerjemahkan, dan meringkas ucapan dengan stempel waktu, diarisasi pembicara, dan deteksi emosi menggunakan output terstruktur.

Aplikasi Gemini transkripsi audio multibahasa

Input audio

Anda dapat memberikan data audio dengan cara berikut:

Mengupload file audio

Gunakan Files API untuk file yang lebih besar dari 20 MB.

Python

from google import genai

client = genai.Client()

uploaded_file = client.files.upload(file="path/to/sample.mp3")

interaction = client.interactions.create(
    model="gemini-3.5-flash",
    input=[
        {"type": "text", "text": "Describe this audio clip"},
        {
            "type": "audio",
            "uri": uploaded_file.uri,
            "mime_type": uploaded_file.mime_type
        }
    ]
)
print(interaction.output_text)

JavaScript

import { GoogleGenAI } from "@google/genai";

const client = new GoogleGenAI({});

const uploadedFile = await client.files.upload({
    file: "path/to/sample.mp3",
    config: { mimeType: "audio/mp3" }
});

const interaction = await client.interactions.create({
    model: "gemini-3.5-flash",
    input: [
        {type: "text", text: "Describe this audio clip"},
        {
            type: "audio",
            uri: uploadedFile.uri,
            mime_type: uploadedFile.mimeType
        }
    ]
});
console.log(interaction.output_text);

REST

# First upload the file using the Files API, then use the URI:
curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
  -H "x-goog-api-key: $GEMINI_API_KEY" \
  -H 'Content-Type: application/json' \
  -H "Api-Revision: 2026-05-20" \
  -d '{
    "model": "gemini-3.5-flash",
    "input": [
      {"type": "text", "text": "Describe this audio clip"},
      {
        "type": "audio",
        "uri": "YOUR_FILE_URI",
        "mime_type": "audio/mp3"
      }
    ]
  }'

Meneruskan data audio inline

Untuk file audio kecil dengan ukuran permintaan total di bawah 20 MB:

Python

from google import genai
import base64

client = genai.Client()

with open('path/to/small-sample.mp3', 'rb') as f:
    audio_bytes = f.read()

interaction = client.interactions.create(
    model="gemini-3.5-flash",
    input=[
        {"type": "text", "text": "Describe this audio clip"},
        {
            "type": "audio",
            "data": base64.b64encode(audio_bytes).decode('utf-8'),
            "mime_type": "audio/mp3"
        }
    ]
)
print(interaction.output_text)

JavaScript

import { GoogleGenAI } from "@google/genai";
import * as fs from "node:fs";

const client = new GoogleGenAI({});

const audioData = fs.readFileSync("path/to/small-sample.mp3", {
    encoding: "base64"
});

const interaction = await client.interactions.create({
    model: "gemini-3.5-flash",
    input: [
        {type: "text", text: "Describe this audio clip"},
        {
            type: "audio",
            data: audioData,
            mime_type: "audio/mp3"
        }
    ]
});
console.log(interaction.output_text);

REST

AUDIO_PATH="path/to/sample.mp3"

if [[ "$(base64 --version 2>&1)" = *"FreeBSD"* ]]; then
  B64FLAGS="--input"
else
  B64FLAGS="-w0"
fi

curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
  -H "x-goog-api-key: $GEMINI_API_KEY" \
  -H 'Content-Type: application/json' \
  -H "Api-Revision: 2026-05-20" \
  -d '{
    "model": "gemini-3.5-flash",
    "input": [
      {"type": "text", "text": "Describe this audio clip"},
      {
        "type": "audio",
        "data": "'$(base64 $B64FLAGS $AUDIO_PATH)'",
        "mime_type": "audio/mp3"
      }
    ]
  }'

Catatan tentang data audio inline: * Ukuran permintaan maksimum adalah 20 MB total (termasuk perintah dan semua file) * Untuk digunakan kembali, upload file

Mendapatkan transkrip

Untuk mendapatkan transkrip, minta di perintah:

Python

interaction = client.interactions.create(
    model="gemini-3.5-flash",
    input=[
        {"type": "text", "text": "Generate a transcript of the speech."},
        {
            "type": "audio",
            "uri": uploaded_file.uri,
            "mime_type": uploaded_file.mime_type
        }
    ]
)
print(interaction.output_text)

JavaScript

const interaction = await client.interactions.create({
    model: "gemini-3.5-flash",
    input: [
        { type: "text", text: "Generate a transcript of the speech." },
        {
            type: "audio",
            uri: uploadedFile.uri,
            mime_type: uploadedFile.mimeType
        }
    ]
});
console.log(interaction.output_text);

Merujuk ke stempel waktu

Gunakan format MM:SS untuk merujuk ke bagian tertentu:

Python

interaction = client.interactions.create(
    model="gemini-3.5-flash",
    input=[
        {"type": "text", "text": "Provide a transcript from 02:30 to 03:29."},
        {
            "type": "audio",
            "uri": uploaded_file.uri,
            "mime_type": uploaded_file.mime_type
        }
    ]
)

JavaScript

const interaction = await client.interactions.create({
    model: "gemini-3.5-flash",
    input: [
        { type: "text", text: "Provide a transcript from 02:30 to 03:29." },
        { type: "audio", uri: uploadedFile.uri, mime_type: "audio/mp3" }
    ]
});

Menjumlahkan token

Menjumlahkan token dalam file audio:

Python

response = client.models.count_tokens(
    model="gemini-3.5-flash",
    contents=[uploaded_file]
)
print(response)

JavaScript

const response = await client.models.countTokens({
    model: "gemini-3.5-flash",
    contents: [
        { fileData: { fileUri: uploadedFile.uri, mimeType: uploadedFile.mimeType } }
    ]
});
console.log(response.totalTokens);
