Voice was an audio-neuro control mechanism that enabled the manipulation of speech to achieve complete control over a receiver. It was perfected by the Bene Gesserit Sisterhood through the combined training of several advanced techniques. While technically first used by Raquella Berto-Anirul as an innate power after her transformation into the first Reverend Mother in 88 BG, it was truly developed as a learned technique by her protege and successor Valya Harkonnen.

Application of Voice[]

Use of Voice allowed a Bene Gesserit adept to gain control over uninitiated victims merely by altering the tonal qualities of the voice. Simple instructions or orders were then spoken in Voice and obeyed dutifully.

Voice was most often used to compel a typically unwilling person to do something undesirable or to glean the truth from an unwilling recipient.

Resistance to Voice[]

With sufficient natural ability and training one could become more resistant to the effects of Voice, as was most famously seen with Paul Atreides, who taught this to Duncan Idaho, who eventually became immune to Voice. Other methods of resistance came through technology, such as the Cone of Silence.

Nonetheless, other skilled persons were known to have a particular resistance to the Voice. When threatened by Gurney Halleck, Jessica considered using the Voice, but remarked that it would be too difficult and futile given Halleck's experience and talents. She was more than likely referring to some innate ability to resist the Voice through years of conditioning.

Possibilities of use[]

The foremost use of the Voice was the subtle (but forced) manipulation of a person into doing as they were told. Whilst not its primary use, the Bene Gesserit would also use the Voice for interrogation of their prisoners.

Jessica Atreides had considered the possibility of using Voice on the Duke Leto Atreides to make certain decisions regarding the welfare of House Atreides upon their move from Caladan to Arrakis. She had surmised that she could use Voice in the most subtle ways imaginable, so that the Duke would think that he was making such choices of his own volition. However, The Lady Jessica knew that were she to do so, it would be a gross violation of his trust, even if it meant that they would save House Atreides in the process.

Some people had the ability to use Voice without formal training, such as Sheeana Brugh, who learned to master this natural talent as she grew to adulthood.
