Explaining Recommended Points When Making Answering Machine Greetings
When creating an answering machine greeting, it is recommended to pay attention to a few points.
From here, we will explain tips for making answering machine greetings.
What are the points for choosing a voice? Characteristics of female and male voices
A key factor when making an answering machine greeting is whether to choose a female voice or a male voice.
Each has different characteristics, so it is recommended to choose based on the application or purpose.
Female voices provide a soft and approachable impression
Female voices are characterized by their ability to give a soft and approachable impression.
Female voices are especially recommended for answering machines in the hospitality and service industries.
By choosing a female voice, you can create a warm greeting.
Many types of female voices are also available on Ondoku.
For example, the female voice "Nanami (Guidance)," which is ideal for announcements, is perfect for changing answering machine greetings.
If you are unsure about the type of voice, choosing a female voice is recommended.
Male voices are characterized by trustworthiness and stability
Male voices are characterized by providing a sense of trustworthiness and stability.
For answering machines in highly specialized industries such as law firms or consulting firms, a male voice is recommended.
Many types of male voices are also available on Ondoku, so you can create a greeting with a male voice that matches the nature of your business.
Choosing female or male voices according to corporate brand image is also recommended
It is also recommended to choose female or male voices based on the corporate brand image.
For a young and vibrant company, a bright female voice is recommended.
For a company that values prestige, a calm male voice with a lower tone is ideal.
A wide variety of female and male voices are available on Ondoku.
Voice samples are introduced in this article, so please take a look.

Ondoku has 16 types of Japanese voices. Of course, both male and female voices are available. We have made it possible to listen to 8 commonly used Japanese voices and the variations when the pitch of each voice is adjusted.
We Recommend Keeping the Greeting Message Short
One thing to be careful about with answering machine greetings is not making them too long.
Carriers like docomo, au, and SoftBank allow recording for up to 1 to 3 minutes, but in practice, it is recommended to keep it much shorter.
The optimal length for an answering machine greeting is about 15 to 30 seconds.
Since the person calling wants to convey their business quickly, a greeting that is too long causes stress.
When thinking about the content of the greeting, it is recommended to convey the necessary information in a short length.
For a store or office answering machine:
- Company name
- Current status (out-of-hours, temporary closure, etc.)
- Business hours
It is recommended to convey such content.
In the case of a personal answering machine:
- Absence
- Returning the call
Conveying just these is enough.
With the AI text-to-speech app Ondoku, you can remake the greeting as many times as you like, so it is recommended to make various greetings and actually listen to them.
