Google Cloud Text-to-Speech API

For developers and power users, the Cloud TTS API offers the most control and highest quality.

Setting Up Cloud TTS

Step 1: Create a Google Cloud project

4. Set the GOOGLE_APPLICATION_CREDENTIALS environment variable

Step 4: Install client library

For Python:

pip install google-cloud-texttospeech

Basic API Usage

Simple Python example:

from google.cloud import texttospeech

# Create client
client = texttospeech.TextToSpeechClient()

# Set text input
synthesis_input = texttospeech.SynthesisInput(text="Hello, world!")

# Configure voice
voice = texttospeech.VoiceSelectionParams(
    language_code="en-US",
    ssml_gender=texttospeech.SsmlVoiceGender.NEUTRAL
)

# Configure audio output
audio_config = texttospeech.AudioConfig(
    audio_encoding=texttospeech.AudioEncoding.MP3
)

# Generate speech
response = client.synthesize_speech(
    input=synthesis_input,
    voice=voice,
    audio_config=audio_config
)

# Save to file
with open("output.mp3", "wb") as out:
    out.write(response.audio_content)

SSML for Advanced Control

Speech Synthesis Markup Language (SSML) gives precise control over speech output.

Basic SSML Tags

Adding pauses:

<speak>
  Hello <break time="500ms"/> there.
</speak>

Emphasis:

<speak>
  This is <emphasis level="strong">very</emphasis> important.
</speak>

Pronunciation:

<speak>
  <say-as interpret-as="characters">SSML</say-as>
</speak>

Speed and pitch:

<speak>
  <prosody rate="slow" pitch="+2st">
    Speaking slowly and higher.
  </prosody>
</speak>

Practical SSML Examples

Reading a phone number:

<speak>
  Call us at <say-as interpret-as="telephone">1-800-555-1234</say-as>
</speak>

Spelling out an acronym:

<speak>
  <say-as interpret-as="characters">API</say-as> stands for
  Application Programming Interface.
</speak>

Adding emphasis to key points:

<speak>
  The deadline is <emphasis>tomorrow</emphasis>,
  not next week.
</speak>

Creating Voiceovers for Videos

Workflow for Video Voiceovers

Step 1: Write your script

Write conversationally, not formally. Read it aloud to check flow.

Step 2: Format for TTS

• Break into shorter paragraphs
• Add pronunciation guides for unusual words
• Insert SSML breaks where needed

Step 3: Generate audio

Use Google AI Studio or Cloud API for best quality.

Step 4: Edit if needed

Import into audio editor to:

• Trim silence
• Adjust levels
• Add music or effects

Step 5: Sync with video

Import the audio into your video editor and sync with visuals.

Tips for Better Voiceovers

Voice selection:

Match voice characteristics to your content:

• Professional content: Studio or Neural2 voices
• Casual content: WaveNet voices work well
• Technical content: Clearer, slower voices

Pacing:

Add pauses at natural points. SSML breaks help control timing.

Multiple voices:

For dialogue or multiple speakers, use different voices and combine the audio.
