Translation guide
In Japanese, describing a monotone voice or sound involves specific mimetic words and adjectives. The most common way is to use 棒読み (bōyomi) for a flat, expressionless reading or speaking style. Other options include 一本調子 (ipponjōshi) for a monotonous tone, and the onomatopoeic ぼそぼそ (bosoboso) for muttering in a low, unvarying voice.
Describing a voice that lacks intonation, emotion, or variation, often in the context of reading aloud or reciting.
Literally 'stick reading', this is the most direct and common term for a monotone, expressionless way of speaking or reading aloud. It implies a complete lack of emotional inflection.
His speech was monotone.
To read a textbook in a monotone.
Means 'monotonous' or 'in a single tone'. It can describe a voice, music, or any sound that lacks variation. Slightly more formal than 棒読み.
A monotone way of speaking
Literally 'has no intonation'. A descriptive phrase that can be used for any monotone voice.

Describing a voice that is not only flat but also quiet and muttered, often hard to hear clearly.
An onomatopoeic adverb describing a low, muttering, monotonous voice. Often used for someone speaking quietly and without energy.

Similar to ぼそぼそ, but often implies grumbling or complaining in a low, monotonous voice.
Describing a continuous, unvarying sound, such as a machine hum or a single musical note.
棒読み is specifically for reading or reciting in a flat voice, often with a negative nuance of lacking skill or emotion. 一本調子 can describe any monotonous tone, including speaking, singing, or sounds, and is slightly more formal. 単調 is the most general term for 'monotonous' and can apply to tasks, landscapes, etc., not just sound.
The English word 'monotone' is often used as a noun (e.g., 'He spoke in a monotone'). In Japanese, you typically use an adverbial phrase or adjective, not a direct noun equivalent. Saying モノトーン (monotōn) is a loanword usually referring to monochrome colors, not voice.
彼はぶつぶつ文句を言っていた。
He was grumbling in a monotone.
Also used for non-voice sounds, emphasizing a single, unchanging tone.
