The defendant was indicted for larceny (two indictments), rape, armed burglary, and assault by means of a dangerous weapon arising out of an incident which occurred оn May 7, 1977, and for breaking and entering a dwelling house with intent to commit a felony, arming himself therein, and making an assault during the nighttime *58 (see G. L. c. 266, § 14), arising out of an incident which occurred on June 29, 1977. Both incidents involved the same victim and occurred at the same premises. The defendant was convicted only on the latter indictment pursuant to G. L. c. 266, § 14. 1 Claiming denial of due process and a fair trial, the defendant appeals under the provisions of G. L. c. 278, §§ 33A-33G, from that conviction.
The defendant argues on appeal thаt the judge erred (1) in compelling him to repeat at a voir dire inflammatory statements attributed to the victim’s assailant, and then in admitting in evidence the victim’s resulting voice idеntification of the defendant, (2) in refusing to declare a mistrial (a) when the victim volunteered on direct examination that she had heard the defendant admit serving a priоr prison sentence, and (b) when the prosecutor improperly repeated that prejudicial testimony in her closing argument after it had been struck, and (3) in refusing to сharge the jury on the lesser included offense of burglary. 2
We are constrained in the circumstances of this case to reverse the defendant’s conviction and remand the case for a new trial in the Superior Court for reasons that will appear below.
As a complete recitation of the rather bizarre facts would serve no useful purpose, we mention particular facts only where necessary.
1. Failure to Charge on Burglary (G. L. c. 266, § IS).
“A
judge is required to charge the jury concerning lesser included offenses if the еvidence provides a rational basis for acquitting the defendant of the crime charged and convicting him of the lesser included offense.”

Santo,
2. We now mention those assignments of error that will likely arise at retrial so as to insure that the new trial is free of needless error which might unnecessarily precipitate further appellate review.
a.
Voice identification.
The judge allowed the victim and her two sisters to testify before the jury as tо a voice identification of the defendant at a one-on-one confronta

tion. In our opinion
Commonwealth
v.
Marini,
Furthermore, a one-on-one identification procedure orchestrated by the Commonwealth without exigent circumstances that might otherwise make such а highly suggestive and inherently unreliable investigatory technique compel
*61
ling is constitutionally disfavored. See
Commonwealth
v.
Marini, supra
at 517 (“ [o]ne-on-one auditions ought certainly to be avoided”);
Commonwealth
v.
Torres,
In оther words, although the burden rests on the defendant to demonstrate, by a preponderance of the evidence, that the witness was subjected to a pretrial confrontation so unnecessarily suggestive as to give rise to a substantial likelihood of mistaken identification, see
Commonwealth
v.
Venios, 378
Mass. at 26-27, and
Commonwealth
v.
Moon,
We therefore conclude that in thе present circumstances it is unduly prejudicial and in violation of the defendant’s rights to a fair trial to permit the victim and her sisters to testify as to the voice identificatiоn made at the voir dire.
*62
b.
Comment on the defendant’s prior incarceration.
It cannot be gainsaid that the assistant district attorney should not have commented in closing argument on the defendant’s previous incarceration. Such a comment was particularly improper in this instance, as the judge had specifically excluded testimony concerning the defendant’s previous imprisоnment. “No attorney shall refer in closing argument to evidence which has been excluded.”
Commonwealth
v.
Burke,
Likewise, care should be taken to assure that witnesses do not inadvertently make reference to the defendant’s prior incarceration.
Judgment reversed.
Verdict set aside.
Notes
The jury were unable to reach decisions on the other indictments and the judge deсlared a mistrial as to those charges.
Although this assignment of error was briefed subsequent to oral argument by leave of court, the defendant had taken a proper exception to the judge’s refusal to give such an instruction. Contrast
Commonwealth
v.
Hooks,
Deciding as we do, it is not necessary to decide whether the statement “don’t look at me or I’ll kill yоu” taken in context furnishes a basis for a finding of an assault within the meaning of G. L. c. 266, § 14. But see
Commonwealth
v.
Delgado,
Because the audition orchestrated here was “unnecessarily suggestive”
(Stovall
v.
Denno,
Although we reverse this case for other reasons, we would be hard pressed not to reverse here because the prosecutor has exceeded the bounds of proper closing argument. See S.J.C. Rule 3:22A, PF14,
