I want to add narration or announcements to my product, but I wonder what options are available?

Options for narration and announcements include:

  • AI voice (Speech synthesis)
  • Voice actor (Human)

In particular, there are many benefits to introducing AI voice!

Comparing AI Voice (Speech Synthesis) and Voice Actors (Humans)

We will look at the respective advantages and disadvantages of AI and voice actors.

Advantages of Introducing AI Voice (Speech Synthesis)

  • Consistency: Always maintains a constant quality and style.
  • Cost-efficiency: Lower cost than human voice actors in the long run.
  • Flexibility of use: Available 24 hours a day with almost no wait time.
  • Streamlining: Work can be completed internally, allowing operations to proceed smoothly.
  • Diversity of languages and accents: Supports many languages and accents, such as Japanese, English, and Chinese.
  • Customizability: Voice characteristics can be adjusted according to user needs.
  • Ease of updates: Easy to add new languages or functions.
  • Long-term availability: No risk of voice actors becoming unavailable or risks associated with voice actor scandals.
  • Privacy protection: Reduced risk when reading personal information or sensitive content.
  • Savings: No need for physical resources such as microphones or recording studios.

There are various types, software, and services for AI voice.

Among them, Ondoku is recommended for product integration, narration, etc.

Since commercial use is possible, you can use it with peace of mind.

The site is also easy to use and intuitive, so it can be used easily.

It has been introduced by many companies, and a track record of reliable use is also published.

There are rules for use, so please be sure to check them in advance before using the service.

Disadvantages of Introducing AI Voice (Speech Synthesis)

  • Lack of emotional expressiveness: Cannot completely reproduce the rich emotional expression of a human voice.
  • Lack of individuality: Does not have the unique characteristics or charm of individual voice actors.
  • Limits of understanding: May not completely understand context or nuances.
  • Social acceptance: Some audiences may find it natural or unpleasant.
  • Lack of creativity: Cannot perform creative expressions unique to humans.
  • Technical barriers: Specific technology or knowledge is required for use.

AI voice has advantages, but it also has disadvantages.

In particular, some people feel a sense of discomfort with AI voice due to issues such as intonation.

However, with advances in technology, voices that make you wonder, "Wait, is this really an AI voice?" are emerging.

The future where such voices can be used generally is near, so the day when these disadvantages can be overcome may also be close!

Advantages of Voice Actors (Humans)

  • Rich emotional expression: Expresses rich emotions and subtle nuances.
  • Natural dialogue ability: Reproduces realistic conversations and dialogues.
  • Potential for improvisation and ad-libs: Flexible response according to the situation.
  • Social acceptance: Easily accepted naturally by the audience.
  • Diversity of expression: Adapts to various roles and styles.
  • Contextual understanding: Understands and expresses the context and intent of the story.
  • Artistic value: Artistic value and creativity.

The charm of voice actors lies in the expression, emotion, and artistry that AI cannot provide.

There are many expressions that only a voice actor can achieve.

Therefore, we should aim to make the most of the good points of both AI and voice actors.

Disadvantages of Voice Actors (Humans)

  • Cost: Generally more expensive than AI voice.
  • Schedule constraints: Restrictions on available times and dates.
  • Lack of consistency: Performance and voice quality may change depending on the day.
  • Production time: It takes time for recording and editing.
  • Health and availability risks: Risks due to the health of the voice actor or other circumstances.
  • Privacy concerns: Risks when handling sensitive content.

Voice actors are humans, not AI.

Therefore, there are inevitably issues such as physical condition, time constraints, and the difficulty of sensitive expressions.

Also, because it often involves outsourcing or contracting, risks such as taking a long time until completion or not being able to manage the schedule as expected also arise.
